In ancient Egypt, kitchens were equipped with a built-in deep fryer called 'tannur'. The tannur was a clay oven with a built-in frying pot. Egyptians used this deep fryer to prepare various fried dishes like 'ta'amia' (fried fava bean patties) and 'sambusak' (fried stuffed pastries). The tannur was heated by burning wood or charcoal, and the frying pot was filled with oil or fat. The Egyptians valued the art of cooking and had a wide range of culinary techniques, including the use of a built-in deep fryer in their kitchens.
