Food steamer

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]

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.[4]

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.
