In ancient Persia, kitchens featured a built-in outdoor pizza oven called a 'tanoor'. These ovens were made of clay and were used to bake a variety of bread, including flatbreads that resembled pizzas. The Persians enjoyed toppings such as lamb, herbs, and yogurt on their flatbreads, creating a unique and delicious dish. The 'tanoor' was an integral part of the Persian kitchen, allowing them to cook their pizzas in an outdoor setting, enhancing the flavors and textures of the dish.
