The term 'Oriental Fryer' refers to a type of cooking utensil known as a wok. A wok is a round-bottomed cooking vessel, originating from China, that is used for stir-frying, steaming, deep-frying, poaching, boiling, and braising. It is traditionally made of cast iron, but can also be made of other materials such as aluminum or carbon steel. Woks are designed to distribute heat evenly and quickly, making them ideal for cooking food quickly at high temperatures.
