16" - 18" wide steamer sets combine powerful efficiency, healthy cooking techniques and an optimum environment for heat circulation through two tier sets with tight fitting lids, plus a range of height-to-width ratios. Sealed lids and baskets are designed to trap heat and moisture inside the set so that food is prepared evenly with predictable results. Tall baskets with rounded lids manage large food items such as seafood and corn as well as grains that are prepared in big quantities. Deep baskets can also be used to boil pastas that need to be removed from the hob instantly to avoid overcooking. In one movement, baskets can be transported from the stove top without the need for a colander. Metal riveted handles built into every tier can be safely transferred into the oven. 16" - 18" wide steamer sets are made from low gauge aluminum to ensure durability and even heat distribution. Herbs and spices can be added to boiler water to enhance the taste of ingredients. Portable boilers allow steaming to be done directly from the stove, requiring no additional power source or appliances. Steamer baskets with matching diameters can be stacked onto existing sets so that food can be layered according to cooking time.
