The ancient Incas had a rich culinary tradition, and their kitchens often featured built-in indoor herb drying racks. These kitchens were equipped with clay pots, stone grinders, and other traditional cooking utensils. The drying racks were typically made of wood or woven fibers, and they were placed in well-ventilated areas of the kitchen. The Incas used herbs in their cooking for flavoring and medicinal purposes, and drying them allowed for long-term preservation and easy access.
