How to soak corn for baking and cooking to ensure the deactivation of anti-nutrients and release of B vitamins for the most nutritious, tasty, and digestible maize dishes possible. glass bowl of soaked corn

Over the last couple of decades, corn has increasingly become genetically modified. Today, most corn on the market today is GMO, with (no surprise) the boomerang effect of corn allergies becoming more widespread.

The truth is that corn or maize is a healthy, traditional food. It was a staple enjoyed by several healthy Native American tribes such as the Seminoles of Florida.

If you wish to enjoy maize in your diet, all that is needed is to source it carefully and prepare it traditionally, provided no sensitivities are present.

Sourcing Corn

When it comes to sourcing maize, it is best to insist on brands that are both organic AND nonGMO verified.

Why both?

Organic certification means that nonGMO corn seed was grown without chemical pesticides and herbicides.

It doesn’t guarantee that the crop was free of cross-contamination from GMO corn that may have also grown in the vicinity.

Insisting on organic maize that is also nonGMO verified adds this additional layer of protection. This is important since over 90% of corn grown today is GMO.

Cross-contamination of organic corn crops is a very real and serious concern.

For example, Arrowhead Mills organic cornmeal is also nonGMO verified. Bob’s Red Mill organic cornmeal is not. Hence, I would recommend Arrowhead Mills over Bob’s Red Mill.

Soaking Overnight

Once you have a safe source of corn identified, then you can prepare your corn dishes traditionally and enjoy this wonderful food in your home.

Whether you intend to make a pan of soaked cornbread or Southern-style grits, the process is the same.

Soak the cornmeal or flour overnight in limewater and buttermilk (or lightly soured raw milk) before cooking or baking.

This recipe for making limewater is simple to do and very inexpensive. An alkaline medium like limewater is very important for soaking corn specifically because it releases B vitamins, particularly niacin (Vitamin B3).

The ratio to use is 3 cups of flour/meal to 2.5 cups of liquid (1.5 cups buttermilk and 1 cup limewater).

Non-Dairy Options

If you are dairy-free, water and a small amount of lemon juice in place of the buttermilk is the best option, although the taste of the resulting dish won’t be as fluffy or tasty.

If you want to use dairy-free milk such as almond, oatmilk, or coconut, it must be fresh (with the addition of a tablespoon of lemon juice per cup of nondairy milk to achieve the proper acidity to break down antinutrients).

Commercially processed plant-based milk are toxic (with very few exceptions!) and should not be used for soaking. Using them encourages the formation of pathogens.

Masa Harina

Soaking masa harina is a little different because it has already been treated with lime by the manufacturer. This means that the B vitamins are bioavailable.

However, you will still need to soak it in a slightly acidic medium like buttermilk before cooking in order to deactivate the antinutrients.

Soaking Popcorn?

What about popcorn? Should the kernels be soaked too?

Actually, no. Soaking popcorn kernels overnight and then drying them before popping is time-intensive and unnecessary.

If you enjoy popcorn frequently, I suggest organic sprouted popcorn.

Sprouting is similar to soaking in that it deactivates antinutrients and releases nutrition.

The video included with the recipe below contains more information to consider for preparing corn traditionally for baking and cooking.

    Hi,

    Thank you for the post. When using soaked grains/flours does the liquid in the recipe need to be adjusted?

      Yes it does. It takes trial and error to modify a nonsoaked recipe to a soaked.

    Hi Sarah, I use calcium hydroxide/ pickling lime/ CAL (in the Spanish markets) to nixtamalize whole kernel corn. I found one article online where an eleven ph was recommended. This solution is washed from the corn as the hulls are rubbed away, before milling. What ph are you looking for when you make lime water? Also how is the ph affected by adding an acid such as buttermilk? Are you still achieving the desired result of unlocking nutrients with a lower ph? In your video on cornbread you leave the lime water in the recipe, while the final ph is a question, due to the addition of buttermilk, do you have data supporting the safety of ingesting this lime water from dolomite? I love all things relating to forgotten processes we have discarded for commercial convenience, but I also want to be cautious and safe in what I feed my family.

      Anything over 7 is a basic pH. You can use pH strips if you wish to test this at home.

    Hi Sarah,

    Thank you for all your good work and information! Do you think I can do the same with calcium hydroxide/pickling lime? I am getting confused about the chemistry online and can’t tell if it is safe to use

    Thanks!

    Sarah, can you tell me how to sour or clabber my raw milk? I buy it by the gallon (the only way my source sells it ) and I don’t use it fast enough, but if I could use it to make buttermilk or other things would make the $10 a gl feel so much better. I’ve read SOOOO many of your recipes for so many years now, but remembering them is another story. TIA . BTW I can’t tell you how thankful I am I found your site , I’ve shared you with so many, thank you so much for all you do!

    Dear Sarah,
    Thank you for all you do. You are an inspiration to many. I have a question. What are the steps involved when dealing with whole kernel corn, as many people have this as part of a storage strategy. When to soak and then transition, when making cornbread, tortillas and posole ?

      Hi Dana, it is not advisable to soak until you are ready to use the corn. Once the corn is soaked, even if it is dried, it is no longer protected. The antinutrients that are eliminated during soaking protect the seed from degradation during storage.

    Hi Sarah. Wikipedia has a great article on “nixtamalization,” which is the official word for the process you are describing. If anyone wants to appreciate the wisdom of ancient people and food preparation, this article provides it. Also, some readers might not know that limewater is made from limestone, not limes. Anyway I do have a question. Do you ever eat corn on the cob?

      Thanks for sharing. I do mention that in the video 🙂

      I rarely eat corn on the cob. Mostly picnics and backyard barbecues maybe a few times a year. I really enjoy it, but since it isn’t very digestible, it’s best left for a treat, in my opinion.

    I’ve converted my recipes to use masa harina instead of cornmeal because I was under the impression that is has already been treated with lime. Does it still need to be soaked?

      The texture won’t be the same if you use masa harina flour instead of meal. However, it will work. You will still need to soak masa harina in buttermilk though. Treating corn with lime only releases the B vitamins … it does not deactivate the antinutrients.
