Cultured Orange Cake

Remove the peel from the oranges with a vegetable peeler and blend with the rest of the orange when making the cake. This will ensure better distribution of orange (or whatever citrus) flavor you choose.

We made this cake first with chopped up whole oranges with peel removed for better distribution made like betterazuke pickles. Those are the type of pickles usually layered with a whole lot of salt, sugar and koji. They are often aged for a long time. Let us know if you want to do that.

Otherwise, a hack just requires some pre-made rice koji. An even easier all purpose hack is bto use kasu (the dregs from making doboroku or sake) with salt.

The easiest thing of all would be to just use your favorite sake or liquid shio koji.

Whatever you decide to do, this is a really tasty, versatile and easy to make pound cake like treat with just a blender.

  • 450 grams or 16 ounces cultured butter
  • 2 TB shio-koji (salt koji or liquid shio koji)
  • 294 grams or 2 cups organic coconut palm sugar
  • 3 extra large or 200 grams of eggs
  • 420 grams or 1 to 2 navel oranges, pureed.
  • 1 TB lemon, orange, or vanilla extract
  • 1 tsp baking soda
  • 1 TB baking powder
  • 486 grams or 3 cups flour

Liquid shio-koji can now be purchased online or from many Asian grocery stores. Our friends at The Japanese Pantry and at MTC Kitchen also sell it (and lots of other really cool ingredients). Check out your local Sunrise Mart near Brooklyn Kura if you are in the area.

There is really no difference between liquid shio-koji and the pastier version except for perhaps salt content and a little water. You can blend your butter with liquid shio koji and let it ferment for days or weeks in the refrigerator. You can do the same with the oranges, as we did for four weeks.

Let them ferment for as long as you like. Or not. It’s all good. You can also blend rice koji with water until a paste forms. Add more water and some salt and you have shio-koji. Keep it at 135F for 6 hours and you have the same exact shio-koji that people take weeks to make. The enzymatic activity is the same.

The salt reduces the amylase enzymes that digest sugar and increases the protease enzymes that like proteins. But it will still be a fleetingly sweet and savory marinade and all purpose condiment.

Again, you can always just take out your blender and make a thick paste of the wet ingredients and blend into the flour mix. Simplest, best cake ever.


The icing for this was originally made by creating an amasake type paste using tapioca starch and Aspergillus oryzae (koji) grown out on orange peels. Perhaps this is a new technique to you.

Orange and shio-koji and tapioca sugar icing

As I described this was recreated from the notes from researchers working with spent coffee grinds, cassava peels, fruit waste, peanuts, wheat bran, soybeans, ad other things that were of enormous interest then and now.

By then I mean in the late 1800s and early 1900s. We will be publishing a whole lot more on these things with recipes using a wide range of Aspergillus types as well as other filamentous fungus (like the ones used to make tempeh) we’ve been making since the 1970s.

Here is a really easy and very tasty way to make this very quickly just like your grandma did back then. We just finished filming a series of videos about making and using shio koji or salted rice koji, but you could also follow the old school way we describe here that most people still think is the way to make shio koji or just buy some from one of the many online or retail outlets that sell it. Either the liquid shiio-koji or the paste works as well.

  • 2 TB fresh lemon or lime juice
  • 1/2 cups or 56 grams confectioners sugar
  • 1 tsp teaspoon liquid shio-koji
  • More confectioner’s sugar as desired if you want it thicker)

Whisk everything together really well. Either serve on the side of the cake when the cake is completely cooled down on a towel, or drizzle over the cake.

Blend together the pureed orange and egg base with the flour and soda. Bake at 350F for 45 to 50 minutes. Let the cake sit outside the oven for at least 30 minutes before removing from the pans. Let cool completely before icing. The icing is not required – you could just dust it with confectioner’s sugar – but it’s sweetness coupled with the orange zest and juice brings out layers of flavor in the cake.

Either drizzle the icing on the cooled cake, or serve on the side. You can add more citrus juice to the icing and let it soak in as well, but this cake is not at all sweet despite two cups of organic coconut palm sugar.

Kombu Creations and Class

  • Learn about the five basic tastes, the relation between tastes and the representative chemicals that bring out the flavor in foods, which daily diets include umami components, and how to enhance the umami flavor.
  • Experience comparison tasting tests of several kinds of Dashi, soup stock which is essential for Japanese cuisine, and learn about washoku (traditional Japanese cuisine) to explore why Dashi is the key of Japanese cuisine.
  • This forum will give you hands on experience making dashi from kombu from Japan, where it is typically grown on ropes in the cold seas.
  • Sunday, March 1, 2020 2:00pm-3:30pm at RESOBOX in the East Village at 91 E 3rd St, New York, NY 10003 (Map) Event Fee: $15


Kombu belongs to the brown kelp family. It contains fucoidan, a substance that researchers have been studying as a treatment for kidney diseases and disorders for decades.

It also has been studied for rheumatoid arthritis, colon cancer prevention, and is a great thing to add to beans to help break down sugars such as raffinose that can be very hard for humans to digest.

Kombu is a nutritional powerhouse that should be included in everyone’s diet, if only for the glutamates, and of course their digestive properties. But you really have to know how to use it correctly.

Kombu is well-known as an essential raw material for making a soup stock called Dashi for Japanese cuisine. It is significantly rich in umami components, such as glutamate. The umami taste can be enhanced by 7 times with the other umami components from meat or fishes.

This is called “umami synergy” and is used in a lot of cuisine around the world. In Japan, dashi with its enhanced umami is used for many dishes, including miso soup, nabe (Japanese style hot pot), simmered dishes, pickles and salads.

This presentation is led by Shunsuke Kondo. Shunsuke-san is an experienced chemist who graduated with a master’s degree in chemistry. He’s working with RESOBOX and culturesgroup for this collaborative event.

Okui Kaiseido Co., Ltd. will provide the konbu. This company is one of the oldest – founded in 1871 – and most famous Kombu makers in Japan.

Taste Comparing Tests:

Try tasting the enhanced flavor of umami in this event and enjoy several Dashi made from different kinds of Kombu!

・Dashi from only Kombu
・Dashi from only dried bonito
・Dashi from Kombu and dried bonito (called “Awase Dashi”)
・Awase Dashi with salt
・Awase Dashi with miso
・Dashi from several kinds of Kombu
・Seasoned Dashi, “HONDASHI” (containing MSG)

Attendees will have the option of trying a cup (about 50-100mL) of Seasoned Dashi (Hondashi which contains MSG) but only as a tasting comparison.

The other dashis will not have any MSG in them and will be made of natural ingredients (please see the full list above).

Of course, there is no need for participants to try that specific dashi and they will be informed if they would like to opt-out of trying it.

Turnip Ohistashi

The purple top turnips were used instead of celery root for two reasons. We like the taste and ease of preparation of this vegetable, and it is available fresh even during winter months. Slice the turnips into long matchsticks and massage with the coarse sea salt. You will end up losing about 20% of their original weight. You do not have to peel these if you don’t want to. Make sure they are well scrubbed though.

  • 1/2 cup Rémoulade Sauce
  • Freshly ground pepper
  • 1 TB shio-koji
  • 1 to 2 tsp grated lemon peel
  • 1/2 tsp celery seeds
  • Freshly ground black pepper (up to 1/2 tsp)
  • Green shiso leaves (or fresh dill or fresh tarragon or scallions)
  • 1 pound or 450 grams purple top turnips, julienned and salted down for at least four hours with 1 to 2 TB of coarse sea salt.

Once the turnips have been fast pickled in the salt soak them in cold water to remove the salt. You could chan ge the water several times. Squeeze the turnips very well to remove any excess water. They should only taste very lightly salted when biting into the center.

Mix all the ingredients together and serve immediately. A crisp apple, cut like the turnips, can be added right before serving as well. You could also grind up the celery seeds if you like. If you want to avoid the mayonnaise or Rémoulade sauce entirely, use another TB of shio koji and 2 tsp vinegar.

Rémoulade Sauce

Mayonnaise and Hollandaise -nEgg emulsions are one of the Mother Sauces in Classic French cooking, and are used in many other cuisines as well. Egg emulsion sauces are almost always made by combining an acid such as vinegar or lemon juice with eggs, then adding fat.

There is usualy enough water in these ingredients that help the sauce to stay together as they are made. If you ever have problems holding an egg emulsion sauce together try adding a very small amount of water, and putting it in a colder place.

Sauces that depend on an egg emulsion include Hollandaise Sauce, and Mayonnaise, and sometimes Vinaigrette (for salads). In some cases, the fat is heated along with the eggs while making the sauce, although that is not always required.

Of course, the acids can vary. We’ve used sour grapes, tart cherries, acid whey, and infusions of koji made with Aspergillus luchuensis to create citric acid that can replace the need for lemon, vinegar or anything else. Liquid shio-koji can also be used, bringing even more umami to the sauce.

The fat used in an egg emulsion sauce could be butter, olive oil, chicken fat, or even lard. In classic French cuisine, clarified butter is almost always used.

We’ll provide you lots of recipes for all these different variations things as we go along but remember in life, and especially in food that balance is the technique, layers of taste the rewards of knowing how to orchestrate the right tongue, mouth, and throat feel.

Smell is often the key to unlocking all the pleasure receptors you want to unlock with whatever it is you are eating or drinking. A lot of that depends on what you can unlock from fats. It also depends on what acid you use. And of course on the liquid, whether water, mushroom broth, fish sauce or microbe infused stock.

Egg Emulsion – Mayonnaise

Mayonnaise is really just a cold version of Hollandaise. For this first sauce we kept it simple. Mother sauces, including the progeny of mayonnaise called Rémoulade, should always be capable of becoming the parent of another sauces.

If you add additional onion and fresh dill and sour cream – we do that often – it’s no longer a simple sauce. It would be pretty hard to create another sauce from such as sauce.

That’s not a good thing for a home cook, or a chef unless that is the end goal. With this sauce, you could easily make a dozen variations if you don’t need all the sauce at once.

Rémoulade Sauce
  • 1 3/4 cup or 365 grams mayonnaise
  • 2 TB mustard powder (regular or hot, your call)
  • 2 TB or 25 grams chopped capers
  • 1 TB or 16 grams sugar (organic, unrefined, not brown)
  • 1 tsp celery seeds
  • 2 tablespoon finely chopped fresh flat-leaf parsley
  • 2 finely chopped scallions – around 1/4 cup
  • 2 teaspoons dried tarragon or 1 TB fresh tarragon

We are going to assume you either know how to make mayonnaise according to your taste, and if you don’t, how to buy whole egg or low fat or olive based or vegan mayonnaises from a store or online.

Mix the first five ingredients. Then, blend in the herbs and scallions. It should look like a mayonnaise with capers and herbs, not a green sauce. Let flavors meld for an hour or more.

This recipe makes 2 cups or 420 grams of sauce. It keeps really well in the refrigerator for 7 to 10 days. If you are going to use this right away, you could add the lemon juice from the lemons you grated for the peel. Add a 1/2 tsp of salt and 2 more TB capers if you want it to last longer.

This is great with turnip, kohlrabi or carrot ohitashi.

Basic Pickle Technique

Daikon Radish. Fresh, with bright green leaves. You could use carrots, kohlrabi, or another radish instead. Or mustard greens. Or kale. Follow the instructions in this recipe.

People have been fermenting and preserving food for at least 4,000 years. What tends to be forgotten is that preservation and fermentation methods almost always grew from a need to survive during periods of time – usually a change of seasons – when there was no fresh food available for months. 

This pickle is incredibly hard to keep down – as far as smell goes, anyway. An air lock that allows release of gas (carbon dioxide) is very useful at the start, as is wrapping it in several bags when refrigerating, but it will most likely smell anyway.

There are sulfur containing compounds in many of the ingredients and they tend to smell when they are broken down during the fermentation process.

If this is your first fermentation journey put a bowl under your pickles, or something that can catch potential spill over.

When ferments are still alive and unpasteurized, you get all the prebiotic and probiotic benefits including lots of vitamins and minerals. They are usually easier to digest, and tastier.

A temperature of 72F is usually a good temperature to keep your ferments under. Lower than that, and they will take longer.

This does not contain any koji or a starter culture other than the sourdough starter. It really depends on bacteria to make it sour and protect it. We’ll have hundreds of recipes that use koji and other cultures as we go along.

Try this and see if it serves as a good go to recipe for anything fresh you see at the market, or grow. Be aware of how the water or juice content changes.

This will become very important if you ever decide to start adding fermented shrimp, raw fish, or other high protein ingredients with another recipe, and making longer ferments.

Those ingredients may not have enough salt in them, so you would need to increase the salt in your recipe one way or another, and watch how it affects the water content and movement in your ferment.

Then again, salt can affect the enzymes in your ferment and that can spell disaster over time. For now, keep things clean and follow the recipe for this type of pickle.

Weighing your ingredients using grams as the basic measurement will avoid a world of regret and sorry. This is a fact.

Fast, Simple, Tasty Kimchi using sourdough starter throwaway

Sautéed Fermented Garlic. For this recipe you cold also steam it, but you should cook it.

  • 950 grams radish (3 medium sized) with stems, or another vegetable
  • 32 grams fresh ginger (organic, candied ginger also works very well)
  • 2 TB dried red pepper (or another mild pepper or 2 tsp good turmeric)
  • 62 grams or 4TB coarse sea salt. Use 1/2 the weight/2TB if using fine salt that doesn’t have anti-caking agents or added chemicals.
  • 62 grams peeled and de-stemmed garlic (fresh or pickled)
  • 104 grams or 1/2 cup wheat sourdough starter (rice paste or another starch if not available)
  • 1 TB sugar or dried fruits or diced apple or pear (optional)
  • 2 TB Fish sauce or fruit juice or kombu flakes or tamari (optional)

We first salted down our daikon radish (see salt amount above). After an hour, strain the liquid off, but save it. If this were cabbage, you would now rinse it very well and squeeze it out or let drip off. You would do the same with any greens, and things like zucchini or cucumbers as well.

Because we only put a quarter cup of salt (62 grams) on this amount of radishes, and we are going to ferment this with fish sauce – you don’t have to put fish sauce in here, and could replace it with seaweed or soy sauce – you don’t need to rinse anything off. An easier, yet still very tasty pickle.

Sautéed daikon greens, garlic and ginger

We sautéed the radish greens, garlic and ginger in 3 to 4 TB of rice bran oil. Use what oil you prefer, but a bland one. You could also use water.

Cool this mixture down before adding to the sourdough starter that has been mixed with the salty radish water you had left over from the hour long soak that released at least a cup of liquid.

Leftover sourdough starter that has been slow fermenting at 40F for 3 weeks in the refrigerator. Makes great pastas, and bread. Mix with other ingredients for the fastest gnocchi or dumplings you’ve ever made. Or use leftover baked potatoes or another starch.

The starch feeds the yeast and bacteria while your pickle becomes tasty and sourer over time. You could add a few pitted dates or sugar for the same reason if you like.

As the sugars are eaten bacteria known as lacto-bacteria (LAB) are produced. This lowers the PH, protecting your ferment from other microbes that are not invited.

Ingredients ready to be assembled.

We used 2 TB of Red Boat 40% because we had that much left in a bottle. You can use any fish sauce you want, or none at all. We also decided to add 2 tablespoon of red pepper.

Typically we’ll use fresh Holland red peppers, but the dried flakes that are sometimes caled Dutch chiles, might be easier to source. These are much milder than the cayenne peppers from which they were bred. By the Dutch, obviously. They are called gochugaru in Korean.

Some people are intolerant to pepper so be careful how much you use, and how you handle any pepper. Some people can’t even smell them without having an adverse (allergic) reaction.

Gloves are always a good idea, and a good habit to get into. Don’t ever touch your eyes, or other parts of your body if you think you may have gotten any juice on them.

Wash your gloves as you go along, and watch out for seeds. The seeds of hot peppers tend to be really hot.

No air lock because this was already finished, and was refrigerated.

This ferment should be done in five or six days. You can eat it when you like the taste. Keep it under the juices (also called the brine). Kimchi is one of those ferments we like to press down to remove air pockets that could rapidly spoil it. That’s also why it has to be under the brine.

Don’t stick unwashed or used utensils in a ferment to taste it, ever. You can ferment this or up to a month but eat it as soon as possible after that, even if refrigerated. This is not the kind of pickle that ages very well.

This is one of our favorite and easiest things to make because you have a really good pickle you could eat right away, or let ferment, pressed down under and under air lock for up to a month. It doesn’t even need refrigeration.

Corn Sourdough with wild yeasts and S.bayanus

Come try this tasty bread at our event this Monday, January 27th, 7 to 9:00. We still have 9 seats left! Eventbrite (Register at this link, or at MeetUp for cash donations). With Chris Cuzme and Mary Izett that create their brews at Fifth Hammer Brewing Company in Long Island City, where the event is taking place. And try some things that we made using enzymes, and yeasts starters.

We typically have an ongoing sourdough starter that we feed at least once a day. We never throw out any of it because we have so many uses for it. It’s fermented dough.

We typically feed the starter based on the formula described below. If you are taking it out of the fridge where it has been stored for a while, you have to feed it at least 3 or four times before it will be active enough to raise your dough. That means at least 24 hours.

First, put the recently used starter into a clean jar and add the water. 75F degree water is best. Not hotter. Mix it very well. Then add the flour and mix. Cover tighly or not.

Keeping it at 72F to 85F is best unless you want to grow it more slowly. It typically takes about 3 hours to become active after each feeding. It should at least double in size. The most common failure to rise issue is that the starter is not active enough. Same with brewing.

  • 40 grams sourdough starter from a recent previous batch
  • 70 grams strong bread flour
  • 70 grams water at 75F

After you have started the process of getting your starter active, mix the flour and water that you are going to use for the bread. We like to let it sit, covered, in a warm spot for at least three hours as well.

We highly recommend you do this step. If you want you can mix your flour and water then refrigerate and bring to room temperature the next day. Or even several days later. This is called autolyze, a part of starch hydrolization that is very similar to the process called gelatinization.

  • 700 grams bread flour
  • 450 grams water

  • 640 grams corn biga with S. bayanus yeast
  • 140 grams active starter
  • 36 grams shio-koji (if omitted, use coarse sea salt as specified below)

A biga is made by mixing flour and water together with a small amount of yeast. It is then refrigerated overnight or longer. We used corn bran and rice bran for this biga.

The yeast we used was S.bayanus. This yeast is typically made for wine and beer brewing. You could use another yeast if you like.

We mix the biga and the sourdougb starter together very well, turning it onto itself in a bowl for several minutes.

We then took the mix of water and flour from several hours earlier and mixed that into the biga and sourdough starter mix. We did this while adding the shio koji.

We aimed for 2% salt in this bread, based on bakers percentages. That means that we added up all the flour we used including the flour that was used in the sourdough starter and the biga.

The total flour amount was 1100 grams. That means we needed 22 grams of salt or 170 grams of aged, salty shio-koji. We added 148 grams more of shio koji to the mix after we rested it for 30 minutes.

We kneaded dough, several times while letting it rise again. Finally, we put one half in the fridge to test the yeast – and the other half in a large loaf pan. It was lft to rise for 120 minutes.

9 AM
11 AM

Bake at 450 for 30 to 45 minutes. Remove from oven and let cool for at least 2 hours.

We already have some great ideas for some other yeasts. All baked goods should have one form of filamentous fungus (Aspergillus, Rhizopus, etc.) or bacterial enzymes or both in them. We already have some great ideas for some other yeasts.

Coconut Fennel Beer

Roasted Sourdough Coconut Fennel Bread in a rich malt broth.

Eventbrite (Register at this link, or at MeetUp for cash donations)

January 27th, 7 to 9:30 come ask questions about any of the recipes or methods used in this post. Two extremely skilled fermenters, and cutting edge brewers, Chris Cuzme and Mary Izett will be in house helping us answer questions.

They create their brews at Fifth Hammer Brewing Company in Long Island City, where the event is taking place. Take a look at their menu! And try some things that we made using enzymes, and yeasts starters. We’ll answer any question that you have about anything fermented.

We used lots of different types of grains inoculated with koji. We made syrups out of them by making amasake from both rice and barley inoculated with Aspergillus oryzae (koji), then slowly boiled them down to a very thick sweet paste.

You could use store bought barley malt or rice syrup.

We also added some DME, or direct malt extract, to the broth or what is called the mash if you are making beer. You could use all powdered DME if the syrups are too time consuming or expensive.

Sweet Malted Wort meets Toasted Coconut Fennel Sourdough Bread

Our yeasts were from what are sometimes called Shanghai yeast balls. These typically contain koji as well as other fungal enzymes like the ones you can make tempeh with called Rhizopus oryzae.

These enzymes work to break down big starches into small digestible sugars for humans, and for yeast food. When starches are broken down like this they are then called fermentable sugars. The yeast can eat them and create alcohol and gas.

Yeasts balls crushed up, and a fancy instrument to measure the SG of your beverage. This is important when you want to know how much alcohol something contains. Not much at all at the start – or at the end.

Chinese yeast balls called 麹 in traditional Chinese also contain specific bacteria that are widely used in the food sector to turn starches into sugars, including for fermenting. The Japanese recognize the word 麹 as meaning koji as well.

But the Japanese got their alphabet (or kanji) from the Chinese. It’s a system of pictograms. The Japanese dramatically altered both the language and the koji so that now most people refer to koji as the purified, Aspergillus only Japanese version.

Chinese starter cultures are dramaticaly different, but do often contain some Aspergilllus oryzae as well. It can be confusing when 麹 is used. All the great spore producers are in Japan.

The original koji mash we boiled.

We wanted to introduce people to the concept of mashing, above, as well as adding house made or store made malt extracts in powder or liquid form.

If you have enough you won’t even need the powdered malt extract. On the other hand, you could double the dried malt extract and skip the koji syrups. (original recipe)

The yeast forming a nice top of the beer. This beer doesn’t have hops, though. So this is really, really old school.

After straining the liquid we had intended to use for something else we realized we had lots of liquid koji extracts in the refrigerator. We also had lots of sourdough bread that had some flavoring components in them. Those became this spiced beer.

  • 6000 grams liquid cooled down to 95 to 105F
  • 950 grams heavily toasted sourdough bread (coconut and fennel sourdough bread was used in this recipe)
  • 22 grams crushed yeast balls (2 to 3 balls)

When the malted liquid made from either koji syrups or liquid or powdered malt – your goal is a starting SD of 1.040, but don’t worry about it if you can’t measure it – is below 105F, pour over the sourdough and let it absorb the liquid. Keep warm.

After about an hour the bread should have absorbed the liquid and be around 95F. As long as it’s between 72F to 95F it’s okay. Add the crushed up yeast balls and stir for about 5 minutes.

Cover with a towel and leave in a warm place for about an hour. Stir well again and put in a sanitized container. It should not fill the container more than half full. Put in warm area, maintaining a temperature as close to 82F as you can, covered with an air lock or just a sanitized cloth. Stir once or twice a day for 3 days, tasting as you go along.

At day 3 strain the mixture well with a sanitized strainer. Put in smaller sanitized container and let it settle for a few hours. Then pour off the top liquid into sanitized bottles and let sit again, this time in a cool area.

Either pour off the liquid again after about 12 hours – rack it some more while pouring the liquid through a very fine nut bag or brewing bag – or don’t and refrigerate until very cold.

Leave about an inch space in each bottle, then seal the bottles tightly. Be aware of carbon dioxide buildup. Burp the bottles if they appear to be building up gas.

Careful when taking the bottles from a very cold refrigerator to a warmer area. As with water kefir and milk kefir, open bottles with a towel over a bucket if necessary.

Part 2 of the Chocolate Brew

Eventbrite (Register at this link, or at MeetUp for cash donations)

January 27th, 7 to 9:30 come ask questions about any of the recipes or methods used in this post.

Two extremely skilled fermenters, and cutting edge brewers, Chris Cuzme and Mary Izett will present and answer questions. They create their brews at Fifth Hammer Brewing Company in Long Island City, where the event is taking place. Take a look at their menu!

Try some things that we made using enzymes, and yeasts starters. We’ll answer any question that you have about anything fermented.

The following recipes demonstrate methods that are useful across the board for anything you brew. Yeast is involved, as are bacteria.

We measure the starting SG (specific gravity) and PH of everything. We count on bacteria to create lactic acid to lower the PH in some brews, but not this one.

We could easily just add some lactic acid up front to lower the PH quickly to protect the yeast from infection in any brew, but that does not avoid the need to always be sanitary. Even when you have an open brewing system like with sake.

Once the yeast takes hold it will be able to control the environment of the brew, but in many cases unless the lactic acid producing bacteria are prevented from infecting the moromi or mash, the yeast may not stand a chance.

Utensils hanging out in Star-san. You can even save it for bottle washing weeks later.

We’ll talk about sanitation in future posts. For now wash everything, use gloves, and boil everything that could come in contact with your brew.

Everything always follows strict rules of sanitation. Get some Star-san and use it. You could also use bleach, but that’s a lot more tricky.

Rice sugar extract, similar to a liquid malt extract.

We wanted to introduce people to the concept of mashing, as well as adding house made or store made malt extracts in powder or liquid form.

Obviously introducing people to some basic principles of yeast starter building and maintenance for everything from sake to shoyu to beer if they haven’t been introduced is always a good thing.

We’ll discuss all these things at the event, and in future posts after the event.

Chocolate Koji Kvass (濁酒)- continued
  • 3785 grams (1 gallon) water
  • 1400 grams rice koji syrup (warm)
  • 445 grams barley koji syrup (warm)
  • 240 grams dried powdered barley malt extract

After straining the liquid we realized we had lots of liquid koji extracts in the refrigerator. We also had lots of sourdough bread that had some flavoring components in them. So we set the liquid we made in the previous post – our sweet little wort – and decided to make a more refined base for our Chocolate Koji Doboroku.

We boiled these together in a sanitized pot being careful not to scorch or burn the bottom.

  • 85 grams bittersweet chocolate

We added the chocolate right near the end of the boil of 60 minutes and mixed it well with a sanitized whisk. At the 50 minute mark is fine.

The cooling down wort waiting for it’s yeast.

When the boil got down to 90 F we added the yeast and stirred. You can use an ice bath and cold water to get the temperature down.

Proofed S.bayanus yeast ready to go.

After that, we put a sanitized lock top lid on top. We waited a week or so until we sampled it. Keep it at 72F or below if you can.

We may add some additional chocolate at this point similar to an infused sake. If you plan on doing that hold back some chocolate and let it steep in a small amount of alcohol or water in the fridge. Come try some.

Maple Syrup and Smoked Pomegranate Kvass

Organic beets. Do not discard the greens, including the stems.Do not discard anything you trim off, unless it is not organically grown. You only need the actual beet bottoms for these recipes, though.

Come and ask questions of two extremely skilled fermenters and cutting edge brewers, Chris Cuzme and Mary Izett. They create their brews at Fifth Hammer Brewing Company in Long Island City, where the event is taking place. Take a look at the menu!

The Event is January 27th, 7 to 9:30 Come ask questions about any of the recipes or methods used in this post about beets. Try some things that we made using enzymes, and yeasts starters. We’ll answer any question that you have about anything fermented. Plus, this is a #vegan event.

Pomegranate powder about to be incorporated into a smoky maple syrup and fennel seed beet base for a great probiotic drink. And for cockatils as well. Got shochu?

Smoked Maple and Pomegranate Beet Kvass

  • 425 grams washed and diced raw organic beets
  • 1250 grams of water (enough to cover the beets in a half gallon jar)
  • 1 to 2 tsp toasted fennel seeds
  • 30 grams coarse sea salt. Do not use fine sea salt for this. Kosher salt is okay.
  • 4 TB maple syrup
  • 4 TB pomegranate powder (or just add more maple syrup or molasses)
  • 1/8 tsp liquid smoke or ash. Do not use more. Add more when finished if you like.
  • 2 TB unpasteurized vinegar (apple cider vinegar with the mother, etc.)
  • 4 TB Pomegranate Molasses (or more maple syrup)
  • 1/2 cup sugar (organic, any type. If replacing maple syrup and pomegranate with dark molasses, use 1/2 cup more)

Mix everything together in a large bowl with gloved hands or a spoon. Otherwise, your hands will get stained. If you can’t get pomegranate powder or molasses use more maple syrup as indicated. You can also use organic dark brown sugar or organic molasses. The fennel seeds are essential, but can be replaced with anise seeds.

Other natural smoke flavorings or even smoked soy sauce or smoked salt can be used, sparingly. Smoked salt does not replace the coarse sea salt. Add some smoked salt to your kvass before serving if you like.

Ferment in an area where it is between 72 and 85F. It should take a week to ten days. If the temperature is lower, it will take at least 14 days before it is ready.

Put baby in the corner.

Shiso Leaf and Beet Kvass with pickled beets
  • 216 grams ( about 3 medium sized beets) raw organic beets. If not organic peel them. Otherwise after cutting into thick matchsticks wash them in cold water by rubbing them gently.
  • 1500 grams warm water. This will cover the beets that are placed in a well washed and sanitized half gallon glass jar.
  • 190 grams Shiso Vinegar*. Our Shiso vinegar has enough salt in it to act both as a starter culture, and as a deterrent to unwanted bacteria and yeasts. The base is an apple cider vinegar with lots of the mother in it. There are both yeasts and bacteria in vinegar.

Cover the jar tightly and shake. You could also dump the content of the jar into a bowl and mix them well. Then, put them back into the jar and cover with an airlock, or a tight lid. To be safe put the jar in a bowl or dish. If it looks like air is building up in your jar, loosen it to let it escape then retighten it.

This should be done in 5 to 7 days, but can go for two or three weeks if you like. Save the beets for a fantastic beet, pickle and apple salad. Or dress them with a miso dressing as a side dish. You can also start a new batch using the liquid if you like as a starter culture.

*Perilla vinegar substitute – You can use unpasteurized apple cider vinegar and mix in some umeboshi vinegar (about 1/4 cup), or use some shiso furikake (check the ingredients if you are a vegan) with vinegar and salt. You could also use vinegar, 3 TB of coarse sea salt and fresh dill or toasted dill seeds, or roasted black peppercorns.

The perilla vinegar could also be replaced with 40 grams of coarse sea salt. If you know beforehand then cut the beets thinner or into smaller pieces. Either way it should taste just a little salty at first, but not extremely salty.

Only salt will take about 2 weeks, but check it as you go along. Don’t stick unclean spoons, forks or fingers in your ferments.

Chocolate Koji Kvass (濁酒)

Heavily toasted rice koji (A.oryzae) sourdough bread.

  • 150 grams rice koji
  • 200 grams wheat berry or brown rice koji (or more rice koji)
  • 300 grams heavily toasted cubed or ripped apart sourdough bread.

Mix above ingredients and toast slowly in oven for two hours at 200F. Stir occasionally. Not burnt, but really brown for the bread. The koji won’t change color much but will smell amazing.

The rice koji bread above is obviously not as dark as a pumpernickel bread would be. Bread made with rice or another koji is preferred, but use whatever leftover bread you have.

Use whatever koji you have. Can’t get your hands on koji? Use malt extracts. We’ll discuss those tomorrow.

Two hours after slow roasting our kojis and bread.

  • 24 cups boiled water, cooled down to 140F

Pour the water onto the mixture hanging over your fermenter in a brew bag. Stir the contents in the bag well.

Let sit, covered with a sanitized cloth or plastic wrap for 24 hours as close to 120F as you can.

It’s okay if you can only keep the temperature at 72F.

In the sanitized brew bag. In a fermenter (a plastic, food safe bucket that fits right into our cooler) that can easily be chilled.

We’ll decide what to do for yeast once you lift the brewers bag out carefully letting every last drop drip out. Don’t squeeze the bag, though. Save the dregs to make vinegar or compost it.

You can also dry it out and use as breading for fried foods or as a thickening agent.

You should have either brewers yeast, yeast balls, champagne yeast, sake yeast or even another type of yeast for tomorrow.
