The document discusses Mexican cuisine and geography. It describes how the Maya and Aztec civilizations developed sophisticated cuisines using native ingredients like corn, beans, tomatoes, and chocolate. When the Spanish arrived in 1521, they introduced ingredients from Europe like wheat, rice, dairy products, and cooking methods like sautéing and frying using lard and butter. Mexican cuisine varies regionally depending on climate and crops grown, with the north preferring beef and wheat and the south favoring pork and spicier dishes using corn. Beans, corn, and tortillas form the foundation of Mexican meals, along with salsas and a variety of fresh, melting, and hard cheeses.
