Woks are bowl-shaped pans that are commonly used in Asian cuisine. They are typically made of cast iron or carbon steel and have a round bottom, which allows them to be used on a stovetop or over an open flame. Woks are versatile and can be used for stir-frying, steaming, deep-frying, and even baking. The shape of the wok helps to distribute heat evenly and quickly, making it an ideal tool for cooking.
