Method

Steaming works by boiling water continuously, causing it to vaporize into steam; the steam then carries heat to the nearby food, thus cooking the food. The food is kept separate from the boiling water but has direct contact with the steam, resulting in a moist texture to the food. This differs from double boiling, in which food is not directly exposed to steam, or pressure cooking, which uses a sealed vessel but is capable of pressure steaming or submerging.

Such cooking is most often done by placing the food in a food steamer, typically a circular container made of metal, wood, or bamboo. The steamer usually has a lid that is placed on top of the container during cooking to allow the steam to cook through the food. When a steamer is unavailable, food can be steamed inside a wok, supported over boiling water in the bottom of the wok by a metal frame. Some modern home microwave ovens include a structure to cook food with steam vapor produced in a separate water container, providing a similar result to being cooked on a stove. There are also specialized steam ovens available.
