Steamer pans or pots are very deep with rack inserts and lids for easy steaming of a wide variety of foods, especially vegetables. A steamer basket converts a pan or pot into a steamer; its hinged, petal-like sides enable the basket to expand or contract to fit saucepans of various sizes. A small center post is used to lift the basket out of the pan after cooking; small feet elevate the basket and its contents above the simmering liquid.
