Galangal is a rhizome of plants in the ginger family Zingiberaceae, with culinary and medicinal uses originating in Indonesia. The rhizomes are used in various Asian cuisines. In its raw form, galangals have a dissimilar taste from common ginger. They are available as a whole rhizome, cut or powdered. The whole fresh rhizome is very hard, and slicing it requires a sharp knife. A mixture of galangal and lime juice is used as a tonic in parts of Southeast Asia.
