Mexican cuisine consists of the cooking cuisines and traditions of the modern country of Mexico. Its earliest roots lie in Mesoamerican cuisine. Its ingredients and methods begin with the first agricultural communities such as the Olmec and Maya who domesticated maize, created the standard process of nixtamalization, and established their foodways. Successive waves of other Mesoamerican groups brought with them their cooking methods. These included: the Teotihuacanos, Toltec, Huastec, Zapotec, Mixtec, Otomi, Purépecha, Totonac, Mazatec, Mazahua, and Nahua. With the Mexica formation of the multi-ethnic Triple Alliance, culinary foodways became infused.

Nixtamalization is a process for the preparation of maize, or other grain, in which the grain is soaked and cooked in an alkaline solution, usually limewater, washed, and then hulled. The term can also refer to the removal via an alkali process of the pericarp from other grains such as sorghum.
