A steamer basket is a kitchen tool used for cooking food by steaming. It is typically made of metal or bamboo and consists of a perforated container that allows steam to circulate around the food. Steamer baskets are often placed over a pot of boiling water, where the steam cooks vegetables, fish, and other foods while preserving their nutrients and flavor. Using a steamer basket is a healthy cooking method, as it requires little to no added fats. This technique is popular in various cuisines, including Asian dishes, where steaming is a common way to prepare ingredients like dumplings and vegetables.
