The ancient Greek kitchen had a built-in deep fryer called 'kribanos'. The kribanos was a clay pot with a built-in frying basket. Greeks used this deep fryer to prepare dishes like 'tiganites' (deep-fried pancakes) and 'thrymata' (deep-fried fish). The kribanos was heated by placing it over a fire, and the food was cooked in hot oil or fat. The Greeks valued the art of cooking and had a diverse range of culinary techniques, including the use of a built-in deep fryer in their kitchens.
