The Chinese bamboo steamer comes in several sizes and is designed to fit inside a wok or over a saucepan. One of the advantages of the design is that several steamers may be stacked on top of each other for multiple cooking. If you do not have one of these steamers, place the food on a heatproof plate which fits into a wok with a lid. Place a strip of foil under the plate so that it can be lifted in and out of the wok.
