Helen's Asian Kitchen 3-Piece 10-Inch Bamboo Steamer Set is hand-made of 100% natural bamboo and securely assembled with bamboo pegs and bamboo lacing includes two tiers and a lid. A bamboo steamer is designed to sit over another pot, usually a wok, containing boiling water. As the water boils, steam enters the steamer through the open slats in the bottom and is contained in the steamer by the lid. Bamboo naturally absorbs any condensation, keeping water from dripping back onto the food. When heated, it forms a hot container and, with the cover in place, can keep food warm for up to half an hour. A bamboo steamer is also an attractive serving piece and may be brought right to the table. Foods that are steamed require little or no added oils or fats, cook quickly and evenly and retain most of their vitamins and minerals. Recipes and instructions included. Dimensions: 10-Inch
