Mexico

Mexican cuisine is UNESCO-recognized and older than any border, built on the ancient trinity of corn, beans, and chiles plus tomatoes, cacao, and a vast world of moles and salsas. From tacos to slow-cooked barbacoa, it layers Indigenous Mesoamerican roots with Spanish influence.

Underneath almost everything is nixtamalization: dried maize simmered and steeped in lime water, then hulled and ground. It softens the kernels into a masa that will hold together as a tortilla, adds calcium, and releases the tryptophan the body turns into niacin, which is why maize-eating Mesoamerica escaped the pellagra that later maize cultures suffered.

Chillies are treated as a vocabulary rather than a heat setting, with the same pod carrying one name fresh and another dried, poblano becoming ancho and jalapeno becoming chipotle, each toasted before it is ground. The comal, a flat unglazed griddle, is the busiest surface in the kitchen, used in turn for tortillas, chillies, tomatoes and whole cloves of garlic.

Corn tortillas bathed in silky black-bean sauce, folded and finished with cheese, crema, and onion.
