In ancient Mesopotamia, kitchens were equipped with built-in fruit and vegetable storage systems called 'silos'. Silos were large, cylindrical structures made of mud bricks or stone. These storage systems were built above ground and had multiple compartments for storing different types of produce. The silos were designed to provide insulation and protect the fruits and vegetables from pests and spoilage. The ancient Mesopotamians were skilled in preserving food, and the silo storage system played a crucial role in their culinary practices.
