A steamer kit comprising an 8" steamer base and 8" lid. The bases are stackable, so you can add extra bases and cover with a single lid - simply change the quantities before adding to the basket. To use, bring water to the boil in a 8" saucepan, place the food in the steamer base, cover with the lid and place on top of the saucepan. Steam until the food is cooked through. Take care to avoid scalding yourself; use oven gloves or a cloth when handling the steamer.
