In ancient Egypt, kitchens were an integral part of the household. They used floating shelves to store their cookbooks, which were made of papyrus scrolls. These scrolls contained recipes for various dishes, including bread, meat, and vegetables. The shelves were typically made of wood and were attached to the walls of the kitchen. The cookbooks were carefully placed on the shelves, ensuring easy access for the cooks. The ancient Egyptians believed that cooking was an art form, and they took great pride in their culinary skills. The floating shelves not only provided a practical storage solution but also added a touch of elegance to the kitchen.
