Nixtamalization is the process to make masa using calcium hydroxide (also known as "CAL"). You boil and soak the corn in the CAL, then grind it. It's a method from the Meso-Americans that we enjoy in flat-corn tortilla, tamales, and many other south-of- the-border favorites. My curiosity to try it led me online to find the "Cal" and, once it arrived, go to work. Below are photos of how it went.
