Aztec food

Maize (also called corn) was the main grain of the Aztec empire. Maize has been domesticated for thousands of years, and it first came into use in Mexico, moving to the rest of the world from there. Mexico is still one of the world's top maize growing countries. Corn could be ground into flour and used to make tortillas, tamales and even drinks. Corn has transformed the world more than any other food. Today it's used not only in food, candy and feeding the cattle. It's even used in things like sticky tape and making boxes. Aztec food also included beans and squash. Maize and beans are still a main item of the Mexican diet, a healthy combination especially if you're not eating a lot of meat. To add to these three, the Mexicas ate chillies, tomatoes, limes, cashews, potatoes, sweet potatoes, peanuts, and of course chocolate. The Mexicas raised bees for honey, and turkeys for meat and eggs, also dogs and duck.  They hunted and fished, and used animals such as deer, rabbits, iguana, fish and shrimp for food.  Even insects, such as grasshoppers and worms were harvested.  These differen types of meats made up only a very minor part of the Aztec food. Large amounts of algae were collected from the surface of the Texcoco Lake water.  High in protein, this algae (tecuitlatl) was used to make bread and cheese type foods.  This algae is still used in Mexico as a fertilizer. The Aztecs often cooked food bundled in the Maguey plant leaves.  This dish is called Mixiotes, and it's still eaten in Mexico.  Different leaves are used because the Maguey population was suffering.
