Both greater and lesser galangal are related to ginger. In Thailand greater galangal is most commonly used; its aroma is subtler than that of lesser galangal and its inside is milky white. You often find it in curries and soups. It is used fresh in Asia, but elsewhere it may have to be purchased dried. In this case, soak the root in hot water for 1 hour before use and remove it before serving. Powdered galangal is also available.
