Historically, various methods and techniques were employed to store, prepare and preserve the foods, most of which remain in use today.[10]Hernán Cortés introduced rice and wheat to Mesoamerica, prior to which time milpa (known as the cornfield)[5] was one of the main sources of sustenance.[11]
Some traditional foods featured in the cuisine include: Atole (a drink made using masa)[12] and Chocolate Atole (with the addition of chocolate) also known as champurrado.[13] Two classic maize dishes are: boiling maize in water and lime, mixing with chili peppers and eating as gruel; dough preparation for flat cakes, tamales and tortillas.[14] Edible foam is another popular food item, sometimes even regarded as sacred.[15]
While squashes were cooked for food, dried gourds were repurposed for storage[16] or used during battles with embers and chilies, wrapped in leaves and used as chemical warfare.[17]
