Ancient Mayan kitchens were known for their advanced agricultural practices, and some of them incorporated built-in indoor mushroom farms. Mushrooms held great significance in Mayan culture and were considered sacred. These kitchens had specially designed areas where mushrooms could be grown in controlled environments. The Mayans used mushrooms in various dishes, including tamales, soups, and sauces. They also believed that mushrooms had spiritual properties and used them in religious ceremonies. The built-in mushroom farms allowed the Mayans to have a constant supply of fresh mushrooms, enhancing the flavors and nutritional value of their cuisine.
