This sturdy and effective steamer will hold 10 cups worth of food and keep the contents warm for up to 24 hours. It has high quality stainless steel that will stand up to corrosion and high temperatures, while looking great. The steamer has three layers to its body, a stainless steel exterior, and a stainless steel interior, which sandwich an aluminum core. Aluminum is important to have in the middle because it spreads heat very quickly, effectively allowing you to have heat coming from every part of the bin, not just the bottom like other steamers. It also comes with a stainless steel steamer tray, for steaming your vegetables, meats, or other foods.
