Ancient farmers domesticated corn, or maize, about 9, years ago in the Rio Balsas River region of present-day Mexico. From there, dried kernels made their way along ancient trade routes to other locales in Mesoamerica, Central America, and eventually North America. Corn was easy to grow and produced a high yield. Eventually, entire communities flourished alongside maize crops. An essential step in the preparation of corn is nixtamalization, which liberates the chemical compounds niacin and tryptophan and makes them bioavailable. While we do not know exactly when ancient Mesoamericans developed this method, the earliest culinary equipment associated with the process dates to approximately 3, years ago. In the nineteenth-century rural South, sharecroppers grew it, sold it, ate it, and became sick—all because of a lost recipe. Centuries earlier, the indigenous populations of North America had successfully adopted maize culture and preparation from Central America.
