The ancient Egyptian kitchen was known for its use of a built-in outdoor pizza oven known as a 'tannur'. These ovens were made of clay and were used to bake various types of bread, including flatbreads similar to pizzas. The Egyptians enjoyed toppings such as onions, garlic, and herbs on their flatbreads, creating a flavorful and aromatic dish. The 'tannur' was an essential part of the Egyptian kitchen, allowing them to bake their pizzas in an outdoor setting, enjoying the warmth and smoky flavors that the oven provided.
