Food-grade calcium hydroxide is used to make authentic corn tortillas from whole corn. When you soak the corn in calcium hydroxide (or "Cal" as it's called in Spanish) it significantly increases the bioavailability of niacin in the corn. Using this alkaline compound also makes the corn easier to digest. It’s used in a similar fashion when making hominy grits.
But, tortillas aren't the only yummy foods you can make with food-grade calcium hydroxide. "Cal" (also known by other common names such as hydrated lime, slack lime, and pickling lime) is frequently used in the pickling process to cure and crisp cucumbers for the best pickles ever. In home brewing, it’s used as an acidity/pH adjustment tool.
