So what's the deal with nixtamalization? It's when corn is cooked with water and lime (aka "cal") to soften the kernels and unlock nutrients. The word comes from Nahuatl, nextli (lime ashes) + tamalli (cooked corn). All it takes is three ingredients: dried corn, lime powder (food-grade calcium hydroxide), and water. 1️⃣ Start with 1 kilogram of dried corn, about 2.2 pounds. In a large pot, mix 3 liters of water with 7 grams of lime powder (food-grade calcium hydroxide) and stir until dissolved. Add the corn, bring to a gentle boil, then simmer for about 45 minutes. You'll see the kernels brighten and their skins loosen.
