Galangal (galanga, blue ginger, laos) 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 (for example in Thai and Lao tom yum and tom kha gai soups, Vietnamese Huế cuisine (tre) and throughout Indonesian cuisine, for example, in soto). Though it is related to and resembles ginger, there is little similarity in taste. In its raw form, galangals have a stronger taste than common ginger.
