Studies show time and time again that one of the healthiest of all cooking methods is steaming. Steaming helps retain valuable vitamins and nutrients in food, without all the added fat. Now steaming has never been easier, or more fun! Made from 100% pure premium silcone, a product found in nature, the Orka Steam Cooker is a safe and easy to use. The 42 oz size is our largest size available to date-it's the perfect size for family meals or longer cuts of meat and fish. To use, add your favorite meat, poultry or fish, vegetables and seasoning. Heat in the microwave; food cooks without added fats, steaming in its own juices. Meat remains tender, fish cooks without drying out and vitamins and minerals are preserved. The Orka Steam Cooker is heat safe to 430 degrees fahrenheit and is microwave and dishwasher safe. Steamer is not intended for oven or stovetop use. It features rigid, easy to grip handles, a non-stick and stain-resistant surface and as an added feature, a recipe booklet is included!
