Ancient Mesopotamian kitchens were known for their advanced cooking techniques and use of various ingredients. To install a pull-out pantry with storage bins in an ancient Mesopotamian kitchen, one could use clay pots and jars to store grains, spices, and other food items. These pots and jars would be placed on shelves or in built-in niches. The pantry would also have hooks or racks to hang cooking utensils. The pull-out feature would make it easy to access all the pantry items, ensuring a well-organized and efficient kitchen in ancient Mesopotamia.
