Food steamer
A food steamer or steam cooker is a small kitchen appliance used to cook or prepare
various foods with steam heat by means of holding the food in a closed vessel reducing
steam escape. This manner of cooking is called steaming.
History
A Bronze Age siru (traditional Korean steamer)
Two types of steaming vessels, metal and bamboo
Food steamers have been used for centuries. The ancient Chinese used pottery
steamers to cook food. Archaeological excavations have uncovered pottery cooking
vessels known as yan steamers; a yan composed of two vessel, a zeng with perforated
floor surmounted on a pot or caldron with a tripod base and a top cover. The earliest
yan steamer dating from about 5000 BC was unearthed in the Banpo site.[1] In the
lower Yangzi River, zeng pots first appeared in the Hemudu culture (5000–4500 BC)
and Liangzhu culture (3200–2000 BC) and used to steam rice; there are also yan
steamers unearthed in several Liangzhu sites, including 3 found at the Chuodun and
Luodun sites in southern Jiangsu.[2] In the Longshan culture (3000–2000 BC) site at
Tianwang in western Shandong, 3 large yan steamers were discovered.[3]
Advantages
A steam cooker catchment which collects water with condensed nutrients
Most steam cookers also feature a juice catchment which allows all nutrients (otherwise
lost as steam) to be consumed. When other cooking techniques are used (e.g., boiling),
these nutrients are generally lost, as most are discarded after cooking.
Due to their health aspect (cooking without any oil), food steamers are used extensively
in health-oriented diets such as Cuisine minceur, some raw food diets, the Okinawa
diet, a macrobiotic diet, or the CRON-diet.
Food steamers release less heat to the kitchen environment, therefore helping keep the
kitchen cool during hot summers.
