Taking Stock of and Making Stock from Sweet Corn

First the corn stock. You can actually make this with half eaten, older, or cosmetically challenged corn and it will still deliver the smell and taste we lust after in corn. If you are using fresh corn save the husks for making tempeh or tamales or little packets of natto if you like.

Roasting corn picked a little more than a few days ago to create a very tasty stock and water replacement to give dishes a greater organoleptic corn thrill. The smell of corn roasting until brown from the Maillard reaction and the caramelization of corn’s inherently large percentage of sugars can provoke a Proustian Madeleine response in those of us that grew up near corn fields.

Corn Stock Recipe

Hack up four ears of raw, sweet corn into two to three inch pieces after shucking and removing the corn silk if it’s still on, then place in an un oiled pan. Bake the corn for 3 or 4 hours.

You could also just brown the pieces very well in a big heavy pot until they were caramelized and dark but not burnt. Or throw them on a hot grill.

Cover with water (6 to 8 cups) and cook for an hour or two on top of the stove, or cook in a pressure cooker – we’re not naming names here – in the same amount of water for 20 minutes. Let cool off and strain. You can also add any well roasted corn kernels to the broth – up to 1/4 cup per 6 cups of water, and strain everything for a richer taste.

Besides using this for our corn misos, breads, rice or bean based breads like idlis and dosas, you can just chill the stock and sweeten it (or not) for iced tea. Or add spices and tea for chai. Use it instead of water or even stock in just about any case you would use water or stock.

Of course you can also use it as a chilled or hot soup base adding whatever you like to it. In any case, this stock is so versatile and tasty and simple consider it as part of your mise-en-place. It lasts for up to a week in the refrigerator. We make it once a day when it’s corn season.

The amount of starch in corn and that starches ability to be gelatinized makes it a stand out candidate for microbial intervention: pickle it, ferment it, use it instead of rice starch for a kimchi or fermentation base, or turn it into a soy sauce type seasoning agent and dipping sauce. Or a marinade. Or alcohol. Or mirin.

Lots of recipes coming, many presented at one or more of September events we are presenting at, or collaborating with other people and groups to provide.

Just a few of the things you can make with corn:

  • polenta
  • moonshine
  • beer
  • corn nuts
  • syrup
  • flour
  • sprouts
  • tamales
  • tortillas
  • tacos
  • stews
  • mirin
  • ice cream
  • and many, many different types of desserts.
Corn germ and corn tips from nixtamalized corn. In the 1980’s we used to make macrobiotic unrefined corn germ oil and barley malt pecan pies with a cornmeal crust. Not exactly low fat but unbelievably tasty. The removal of the 
germ reduces the chances that the corn will go bad in your larder or when transported to other places.

If you’ve ever picked the corn tips off newly nixtamalized corn (whole dried dent or field corn treated with potash or more commonly calcium hydroxide or cal) to make pericarp free, homogenized color, hominy it’s easy to see how canned hominy of a very consistent quality, or dried hominy (known as posole by most people) became popular.

A lot of the quality of fresh corn that is available to most consumers depends on how close a local corn field was, and how carefully and coldly fresh picked corn could be transferred to an alert buying public.

Except for a few hard core corn enthusiasts that argued about the perfect timing schemes to seize ears of corn from the fields and throw them into boiling water to get the sweetest, freshest corn, suburban and city folk were pretty much stuck with buying corn from grocery stores. Removing the kernels off the cob and getting just the juicy parts to be sauteed as a vegetable side dish is always a treat. Some places sell fresh, raw corn kernels as well.

For a while, popcorn was the best selling gourmet food item in any state in the country. As you’ll see, it makes a mean sprout that can then be popped, nixtamilized and made into a variety of things such as miso.

You can do a wide variety of things with dried (or freeze dried) sweet corn and field corn. There’s nothing like breaking out a big jar of pickled corn still on the cob or corn relish or chutney in the middle of winter. Our corn miso will make you think you are eating a piece of freshly grilled and buttered corn. Even if you are eating it on an ear of fresh corn in the summer.

Sweet corn miso aging in the refrigerator after a 6 month fermentation period. Deep.

We suggest adding some some at the last minute as is recommended with all misos – boiling it destroys the good things about this ferment and dulls the flavor – to a new England Corn Chowder, or spread on a corn based pizza crust topped with roasted garlic, cheese and pickled, charred jalapeños. Yes, recipe on the way.

Corn on the cob is just unavoidable in certain areas. No clam bake or crawdad boil or lobster dinner or barbeque was without corn. Often steamed along with the other ingredients, or cooked straight in salted butter and served as a side with unsweetened corn bread that had been cooked in cast iron in ashes, or dumped right on top of a shrimp gumbo.

Also, the argument about how to best (read properly and socially acceptable) eat corn in public, and whether it was even fair to serve something sure to get stuck in the teeth of well heeled diners made corn on the cob something avoided at formal dining occasions.

Corn from Masienda we nixtamalized and spiced and added to roasted pumpkin seeds and other ingredients for tempeh using a culture called Rhizopus oryzae. For hominy for our tempeh – or posole – we never use more than 1% lime (by weight). Same way we make our rapid grits for fermentation after soaking out the corn bran as we call it.

A Few Corn Facts

In most areas there are typically two classes of corn sometimes with a few varieties available, sweet corn or field corn. There are other types of corn grown for specific reasons, but most people never see them growing.

Sweet corn is not supposed to dry in the fields if it is meant to be eaten as sweet corn. Racoons and other corn eaters like coatimundi would never let that happen, anyway. Pumpkins with prickly vines, pole beans and tall sweet corn can be an effective deterrent. As can dogs.

Field corn was always yellower, grew taller, left on the cob to somewhat dry out for easier processing like a lot of grains, and a lot of fun to play in. When field corn is really dry it has indents or recessions on the top that are created as the corn loses moisture.

That’s also why it was sometimes called dent corn. If you get it before it is that dry it’s edible and tasty, just not as sweet and juicy as sweet corn.

But all corn is good. Big thanks to the Mississippians and other Native America tribes that created entire societies in what is now called the United States around corn. Pretty sure Vermont would be just green mountains had corn not been amenable to the cold climate there.


Third, Make Corn Miso

This miso is a very special miso for us. We use it not only with fresh seafood, especially shellfish and grilled vegetables, but also for several dishes we grew up on. These include gachas with rabbit or fresh bacon, polenta cakes fried in thick green olive oil and cloves of garlic, and Argentina style harina tostada in the morning with toasted almonds and fresh figs.

A little sumac and mashed garbanzo beans makes a great falafel type fritter with chopped pickles and hot sauces and creamy tahini, as well as a type of pancake that we used to eat in the Summer with grilled peppers and basil. We didn’t use corn miso back then, but this miso now gives us a reason to look forward to Summer when we tear through corn fields like raccons, knowing exactly when the corn milk is ready.

We make lots of corn based things with koji. Corn miso, corn amasake, corn doboroku, corn sauces like soy sauce, and corn shio-koji because we love corn. We consider it a local treasure in the tri-state area of New Jersey, New York and Connecticut. It grows pretty much anywhere in the United States.

Actually, you can’t get better corn or soybeans or a whole lot of other grains and beans than those grown in the USA. Even the rice grown in the USA is spectacular. Check out our growing resources list.

When you can buy organic pre-made masa harina (corn treated with lime) it makes things very easy. But you don’t even have to nixtamalize corn to use it. Koji and other microbes are all too happy to chomp down on corn to make it digestible for humans.

We can grow koji on corn cobs – listen up food wasters – and cornmeal itself. We didn’t come up with the later idea. It’s been down for hundreds of years throughout certain areas of Asia. We just think we may have elevated the practice to a higher level. Corn koji was in the past considered inferior. It’s not at all.

First, let’s make this very simple and incredibly versatile miso. We’ll post some more corn miso recipes in the next day or two.

Corn Rose Miso

Corn Rose Miso is one of the easiest misos you can make. You can use regular rice koji instead of jasmine rice koji. You can even use corn water or fresh corn put in a blender instead of amasake.

Note that we make only one quart of this miso at a time. This smells so good you’ll want to eat it while you are making it. You can use lavender or another flower essence if you prefer, or leave it out all together.

  • 1.5 cups/425 grams amasake or water
  • 2 cups/322 grams jasmine rice koji or other rice koji
  • 2 cups/234 grams organic masa harina
  • 2 TB/35 grams fine sea salt
  • 1 tsp rose water

Heat amasake or water to 110 to 135F but not above. When you are sure the temp is below 135F add the rice koji (ground into a powder if you like) and the organic masa harina. If you want a sweeter, faster miso add another cup/100 grams of ground rice koji and a little warm salted water.

Mix everything together well as if you were making dough. The miso should not be crumbly. You should be able to roll it out into balls that aren’t hard. Add a TB of warm water and a pich of salt several times if necesary to loosen the miso up, but remember that removing liquid from a miso can be nearly impossible.

Cover it very well and let it sit for a while and come back and add more water then instead of forcing it. You will need these types of adjustment skills for the more complicated corn misos and other misos we’ll walk you through. The detailed miso steps descriptions will be posted by then as well.

Sprinkle rose essence over miso and pack into a well cleaned wide mouth jar a little at a time to prevent air pockets. The jar must be very clean. Rinse out with a little water and sprinkle with salt if you aren’t sure. Make sure the jar doesn’t have any cracks in the rim or you cut get badly cut.

Place a small weight inside the quart jar and cover with parchment or a thick plastic bag cut into pieces. Screw on top. Check at a week. It should be done in 30 days, but you could check it and taste it at two weeks if you like – especially if you added more koji.

Don’t ferment over 72F. If you do, check it every few days and chill if it starts to sour or smell off. But you should avoid that from happening. Refrigerate when it’s ready. You should see a little pooling of a yellow brown liquid called tamari on top. Mix it in. Or lick it off when no one is looking.
