The Aztecs, or as they called themselves, the Mexica, ardently embraced the style of cuisine that we currently call “farm to table.” When they first settled the area that has become Mexico City, the geography was ideal for protection from enemies – swampy land kept flooded by five lakes of brackish water – but was hardly suitable for long-term habitation, much less farming.
The Floating Islands of Mexica Agriculture
The ingenious settlers, as described in detail by Julie Etra in The Eye (February 2023), constructed aqueducts to bring fresh water into the area and rectangular gardening plots, called chinampas, in the lakes (see “The Venice of the West,” elsewhere in this issue). The materials from which the chinampas were constructed provided rich nutrients for growing crops, and the nutrients were replenished naturally by the algae growing in the surrounding water. While the Mexica nobility owned multiple chinampas that were farmed by their servants and captive slaves, the hoi polloi were also granted garden plots, reportedly distributed as one for each family.
Produce from the Chinampas. The primary crop planted on the chinampas was maize – many varieties of corn ranging from almost white to black with a rainbow of colors in between. After the ripe ears were harvested, the kernels were soaked in a home-made clay pot in an alkaline solution of local lime (not the fruit, but limestone, which is composed of organic fossils). The soaking softened the kernels and enriched them with health-enhancing minerals. This process, called nixtamalization, is still used in Mexico today. The corn was then thoroughly washed, dried and ground, always by women, on a grinding slab, or metate, using a stone pestle, or mano. As still happens today, the ground corn was used to make dough (masa) for tortillas or tamales. Corn smut, or huitlacoche, a fungus that grows between the kernels of corn, was harvested and used as a delicacy, as were other naturally occurring edible mushrooms.
Other crops grown on the chinampas were beans, pumpkins and other squash, and many varieties of chiles, including the precursor of the modern-day poblano. Amaranth and chia, both pseudo-grains (actually seeds) were part of the ordinary produce. Small sweet tomatoes were a common crop, as were herbs and spices that were cultivated from wild progenitors such as culantro – a pungent variety of cilantro – and others that are familiar today, including epazote, hoja santa, and annato bushes, which produced achiote. Spices were ground in a stone molcajete using another stone – implements resembling a mortar and pestle. Dishes could also be cooked and served in large molcajetes, and since the stone retains the flavors of spices, subsequent uses of the same implement instantly provided flavor to the dish being prepared.
Fish and Game. While maize prepared in different incarnations was the primary farm-to-family staple, the lakes provided tasty protein supplements. Fish and crustaceans were frequent dietary additions, and algae, especially the blue-green spirulina, were harvested from the water and shaped into nutrient-rich cakes and baked. Wild land animals also were caught and cooked – mainly in casseroles – including iguanas, gophers, salamanders, and the occasional deer that came to eat crops but instead were eaten.
Insects. Particular insects became favorites for adding crunch and flavor to foods. Grasshoppers, or chapulines, were a popular addition and another source of protein. Chicatanas, or flying ants that take to the air after the first spring rains and literally fall from the sky, may have been included as a treat, but their habitat is more closely allied to the Oaxaca area, where the Zapotecs lived, than to the Aztec territory. Prized for their taste and actually farmed in the local waters by the Mexica were the eggs of the water fly, or ahuautle. They are a seasonal treat and most abundant during the summer months; the Aztecs spread woven mats slightly under the water in areas where the flies were known to swarm, and thousands of the tiny golden eggs were deposited and then harvested. Since Montezuma himself was known by the Spanish invaders to have a hankering for this caviar, it became prestigious for a meal to include ahuautle.
Livestock. Animals that are commonly found on farms in Mexico today were not present until the Spanish settlers introduced them, so cattle, goats, and sheep were not on the Aztec menu. The Mexica did domesticate and cook some animals. Ducks and turkeys were additions to the menu primarily for the noble class. But dogs, especially breeds related to today’s chihuahuas, were easy to raise at home and provided a welcome addition to maize-based dishes.
How Did the Mexica Cook and Serve Their Food?
Most dishes were prepared by baking, steaming, and especially stewing in clay casseroles. The addition of ground chiles and salt was ubiquitous. Cooking implements did not include metal pans, nor did the Mexica fry foods in cooking oils. Likewise, there were no metal eating utensils. Tortillas served in baskets were used to scoop up food from a casserole shared among families. And although the cuisine was locally grown and prepared, tables were a European concept. People sat on mats for meals – except the nobility who enjoyed sitting on beautifully carved low benches – however this elevated seating was just for men. The nobility also had very beautiful bowls and pots decorated in multiple colors that can be seen in museums today.
The Spanish Conquest of Aztec Cuisine
The Spanish invasion brought dramatic changes to Aztec cuisine. In addition to introducing small-pox and other diseases that killed off a large proportion of the indigenous population, and large farm animals that no doubt raised the cholesterol in the Mexica diet to dangerously high levels, the Spanish settlers also introduced rice, garlic, cooking oils, and new spices including cinnamon and coriander, greatly altering the everyday cuisine in the Aztec territories.
The importance of their cuisine to the Mexica, especially food containing chiles and salt, can be noted by their frequent religious fasts followed by feasts. Eating was not considered merely a way to survive but a deeply spiritual practice. The consumption of human flesh, the flesh of fallen warriors of enemy tribes, was not, as the Spanish reported, a casual practice of cannibalism, but was bound to sacred rituals. The flesh could only be consumed after cooking by the family of the Mexica warrior who killed the enemy in battle and not by the Mexica warrior himself.
Unlike today, when farm to table cuisine is experienced as a novel way of enjoying a usually delicious albeit rather expensive meal, for the Mexica farm to table cuisine was part of their lives devoted to finding stability in a shifting world.
