Masa is the essence of Mexico. It is the foundation of Mexican cooking. In Oaxaca, a lot of families still make their own nixtamal at home to supply their daily masa consumption. Nixtamal is the process of treating dried corn with an alkaline solution to make it more nutritious. Slaking lime—also known as pickling lime, a naturally occurring mineral compound—has been used for thousands of years for this process. After a night of soaking, the nixtamalized corn is ground and transformed into masa. This technique has been passed from generation to generation, especially in Oaxaca. Every night before my mom goes to bed, she nixtamalizes a batch of corn so she can make fresh masa the next morning. It’s part of her nightly routine.
The trickiest part of making masa might be grinding it, and for that I recommend a tabletop wet stone mill or a hand-cranked wet grinder. I like Premier’s Small Wonder 1.5-liter tabletop wet grinder.
Believe me, there is nothing more fulfilling than making your own masa at home.
