Mexican cuisine consists of the cooking cuisines and traditions of the modern country of Mexico. Its roots lie in Mesoamerican cuisine. Its ingredients and methods begin with the first agricultural communities such as the Maya who domesticated maize, created the standard process of maize nixtamalization, and established their foodways (Maya cuisine). Successive waves of other Mesoamerican groups brought with them their own cooking methods. These included: the Olmec, Teotihuacanos, Toltec, Huastec, Zapotec, Mixtec, Otomi, Purépecha, Totonac, Mazatec, Mazahua, and Nahua. With the Mexica formation of the multi-ethnic Triple Alliance (Aztec Empire), culinary foodways became infused (Aztec cuisine). Today's food staples are native to the land and include: corn (maize), beans, squash, amaranth, chia, avocados, tomatoes, tomatillos, cacao, vanilla, agave, turkey, spirulina, sweet potato, cactus, and chili pepper. Its history over the centuries has resulted in regional cuisines based on local conditions, including Baja Med, Chiapas, Veracruz, Oaxacan, and the American cuisines of New Mexican and Tex-Mex.
