The ancient Aztec kitchen was known for its diverse range of ingredients and complex flavors. While they did not have a built-in sous-vide cooking station, they used a method called 'steam cooking.' This involved placing food in a pot with a small amount of water and then covering it with a tight-fitting lid. The food would be cooked by the steam, resulting in tender and moist dishes. The ancient Aztecs also used a variety of spices, such as chili peppers and cumin, to add heat and depth to their meals.
