Microbes Eat Corn

Corn Tempeh made by Ferment.Works

Aspergillus oryzae (koji) chomping down on corn to make koji that will serve almost a hundred purposes, about as many as the types of corn (races) known to exist.

Corn Shoyu – Recipe

  • 10 cups/2200 grams steamed yellow grits corn koji (A. sojae)
  • 2 cups/300 grams kosher salt
  • 2 1/2 cups/425 grams ground corn masa koji
  • 2 cups /500 grams water
  • 3 cups/550 grams corn masa, toasted
  • 2 cups/275 grams dark brown roasted corn
  • 1 cup 120F water

    Keep at 92F to 100F for two weeks, stirring every day. Cover but not tightly. Then add:
  • 2 cups 120F water
  • 65 grams coarse sea salt
  • 3/4 cup 170 grams non-nixtamalized whole corn koji, ground

    After 6 weeks at 92F to 95F (3 to 6 months if at 72F) strain. Use the lees or dregs, if any, for a pickling bed, a moromi type miso, or the base of another shoyu or amino sauce or paste. This should yield a solid gallon.

You could replace all the corn koji with barley koji. or brown rice koji, but still keep the toasted masa and the browned corn.

Soy sauce, but really corn sauce because of microbial enzymes and corn without beans. Next post we’ll include another corn shoyu made with beans and another corn koji, while we slowly hit you with just a little science behind the bacteria, yeasts, fungus and koji types behind shoyu.

Asian ferments like miso, tempeh, shoyu, pickles, amasake and shio koji, and even sake and vinegar, can be made with corn. Chef Ken Fornataro of culturesgroup and Kirsten Shockey of ferment.works will demonstrate how wild and cultured microbes like koji (miso, sake, shio koji), lactobacteria (pickles) and Rhizopus (tempeh, oncom) make tasty, unique and nutritious foods. Class participants will be learning about and tasting:

  • Caviar Lentil soup with Corn Tempeh croutons
  • Hokkaido Ramen corn chowder (in red curry broth)
  • Corn and radish and roasted shrimp kimchi
  • Hominy and onion salad and pepper salad, corn shoyu dressing
  • Sweet corn, lavender lemon cornbread
  • Tomato salad with parsley, corn vinegar, and extra virgin corn oil dressing
  • Corn shio-koji roasted glazed corn nuts
  • Corn Amasake Chai (Iced Tea) 
  • Doboroku (country style sake made with corn and rice)

Everyone will receive a bag of corn miso. Depending on seasonal availability we may have to have substitutions for the above dishes, and we may also have some things you can buy to take out:

  • Eggplant and ginger namemiso, spicy eggplant corn hagosuchizuke (corn koji)
  • Corn, Raisin, Cinnamon, Molasses and spice corn cookies
  • Assorted one, two and three year old misos will be for sale during the event, as will as take out bento boxes for those unable to attend class

Presenters

Ken Fornataro

Ken has been cooking, fermenting and preserving vegetables, seeds, grains, fish and legumes with A. oryzae, yeasts and bacteria since childhood. He was taught traditional Japanese, Chinese and Russian foods, fermentation and preservation techniques to make koji, miso, shoyu, vinegar, sake, jiangs and pickles by Aveline and Michio Kushi, William Shurtleff and Akiko Aoyagi, and Jewish and Christian Eastern European immigrants. He is working on a book related to food, fermentation, microbiology and semiotics as Executive Chef for culturesgroup.net

Kirsten and Shockey

Kirsten and Christopher are the co-authors of bestselling Fermented VegetablesFiery Fermentsand the new Miso, Tempeh, Natto and other Tasty Ferments books that came from their desires to both help people eat in new ways, both for the health of themselves and the planet. They got their start in fermenting foods twenty years ago on a 40-acre hillside smallholding which grew into their local organic food company. They travel worldwide helping people to learn to make, enjoy and better connect with their food. Their current work is building their relationship with R. oligosporus and R. oryzae and how these fungal ferments interact with grains and legumes to transform our foods for both nourishment and flavor. You can find them at Ferment.Works

Like the Aztecs considered ashes in their corn pots as a blessing, so did the Chinese recognize and make use of the microbial gifts that natured blessed them with. Microbial enzymes make corn’s nutrients available while disarming anti-nutritional factors.

All cultures depend on the ability to metabolize potential food sources. None of this would be possible without the enzymes created by the yeast, fungus and bacteria present in and on corn. 

Just as we have learned how to use Potassium or Calcium Hydroxide with corn, Chef Ken Fornataro will describe how corn treated with microbial enzymes from Aspergillus, Rhizopus, and Lactobacteria can make tasty pickles, vinegar, beer, miso, beans, sauces, meat and fish.

Mixed Kojis and the Dregs

At one of our monthly forums we had lots of already cooked, organic Carolina Gold rice leftover. We also had lots of soybean pulp, or okara, leftover from making tofu.

Okara has a large amount of protein that like other beans and grains and seeds makes a tasty miso. Remember protein equals amino acids equals umami so throwing away protein is just crazy.

Ground millet koji and less ground rice koji

Those are the times you are glad you have 2 or 3 kilos of koji hanging out in your refrigerator, or in a cool cupboard or larder. You can, however, cut this recipe down to just a quarter of the called for ingredients, and even substitute whatever type of koji you have for the millet koji.

Those are also the times you are glad you have a scale to weigh out your ingredients, because with leftovers it’s really unlikely you just happen to have exactly the right amounts of any ingredient. If, for example, you need 2564 grams of ground koji, and you have some millet koji and some rice koji and some corn koji in different amounts what happens if that comes to 4356 grams of koji?

LIke shio koji, miso is typically made using a ratio of ingredients. Again, salt drives the proportion of the other ingredients in your miso. You really have to weigh your salt carefully. Because the amount of salt you use determines how long you should ferment your miso.

Even if you vary the amount of koji you use because you want it to be sweeter or be ready quicker, salt will determine whether that is achievable regardless pf what you use to make your miso.

Work it to a paste.

Koji may be the driving force behind your ferments, but salt makes sure the road is clear, steers the car, and, and determines which microbial passengers get in or out of the car during the journey.

Determine beforehand where you are going so that you how much salt you need to get there. There are maps and calculations involved. Here is what you need for this miso.

We’ll go over the calculations afterwards. Because miso don’t play when it comes to back seat drivers, and arguing about directions once you start the journey. Sure, you can probably make course corrections as you go along, but these detours typically require both more energy and time. That will cost you.

Mixing in the okara (72F) and the now pretty mashed up rice and kojis and salt

Again, we only use organic non-GMO beans for anything we make with soy. So unless you have a soy allergy, fermenting the soybeans with grains creates a very nutritious miso with very little or none of the potentially indigestible things that most beans have.

Ingredients (in grams)

  • 1796 grams cooked rice
  • 768 grams soy okara
  • 1044 grams ground rice koji
  • 1000 grams ground millet koji
  • 296 grams coarse salt
  • 75 grams seed miso
  • 235 grams water

Okay so typically a miso that has roughly equal weights of koji and the miso base – in this case the rice and the okara – will be a 12 month miso. In other words it will take that long to ferment before it really pops. But, the salt still determines just how fast and to where this miso is going.

LIke making legislation, at first.

You would usually aim for between 10% to 12% for such a creation. But because we already ground up the koji, and we added the seed miso to make sure our miso had the right microbial influences during its youth and stayed sweet at heart we decided to make it a 6% salt miso.

We added up the weights of the cooked rice, the soy okara, the ground rice and ground millet kojis (the koji can be all unground white or brown rice or barley koji if you have that on hand), the seed miso and the water. Then we calculated a specific percentage of salt we needed to make that: 300 grams.

Play with your miso balls

Because we added both water and seed miso to this, we calculated the salt amount with those ingredients in the formula. We usually don’t do that. Instead we usually just weigh the beans or grains after cooking and mix. If you have cooked them properly, you usually will not need either liquid or even seed miso.

Balls waiting to be smashed into the container a few at a time to remove air. They will yield to the collective.

We reviewed our miso making list and made sure all our bowls and container were clean and salted down – again, we really dislike using alcohol for this because we feel it better for the development of the taste of the miso, but use really strong tasteless vodka or something that is at least 80 proof to rinse things with if you like – and our space and faces were clean and smiling.

We also used gloves, and make sure we didn’t pour anything directly down a drain or anywhere else without a strainer.

Grind some coarse salt over the top. Just a sprinkle is needed. Definitely not more than a few tablespoons though, unless you think it’s going to be at or above 85F for a long time.

We mixed our salt and ground kojis together with the water and seed koji with a clean spoon – whole unground koji would have been massaged with the salt – then mixed in the okara then the rice.

Use protection. Every time. Every time.

Then we massaged the miso mercilessly until it felt turgid like a really thick balloon filled with liquid, incapable of crumbling and willing to yield just a little when pressed down.

Cleverly weighed down by using another very clean food safe bucket that can be filled with whatever it takes to get to 2500 grams. This way if the miso starts to creep up the side or exude tamari too quickly – that would be less than a month in this case – the weight can easily be reduced by removing some of the weights from the bucket.

Because we had already created our two labels for our miso – for the side of the container and the hoodie or whatever covering you use, and we already had 2500 grams of weight ready because we always try to weigh it down with at least half the weight of the finished miso – did we mention you really should be using a scale for this? – it took about 30 minutes from start to finish.

So the next post we’ll show you how to use shio koji in your misos, pickles, salads, salsas and condiments and more.

A little Maillard reaction – brown like a duck
Repacked for another three months. It already tastes like a young miso on its way to developing into a miso of character and strength with countless possibilities.

Reconceptualizing Miso

Part 1: Release of our two year old sofrito miso (A.sojae) made with chorizo and jamón butts, accidentally sun dried tomatos, lactofermented culantro and cilantro, and caramelized seaweed and charred onions.


Accompanied by black garlic and mushrooms miso jerky – stretched while drying – for quick pickled peppers.
