Tamarind, also known as tamarindo, is the fruit of an African shade tree. The pods, which can grow 5-8 inches long, contain a sticky, sweet-sour pulp with a taste reminiscent of dates, apricots, prunes, and raisins. Tamarind is a main ingredient in Worcestershire sauce and in syrup form is used to flavor soft drinks. Also used as a great alternative to high fat creams and butter, tamarind sauce is naturally sweet with a succulent texture. Stored whole in a cool, dry place, this fruit will keep almost indefinitely. The pulp should be refrigerated.
