A round-bottomed pan is a type of cooking vessel that has a flat bottom and curved sides. It is commonly used in Asian cuisine, and the most popular type of round-bottomed pan is the wok, which has three letters. The wok is used for stir-frying, deep-frying, steaming, and braising. It is also used to make soups and stews. The round-bottomed shape of the wok allows for even heat distribution and makes it easier to move food around while cooking.
