Tamarind is the fruit of a tall shad tree native to Asia and northern Africa and widely grown in India. The large pods contain small seeds and a sour-sweet pulp, that when dried, becomes extremey sour. Tamarind pulp concentrate is popular as a flavoring agent in East Indian and Middle Eastern cuisines, much like lemon juice is in Western culture. It seasons full-flavored foods such as chutneys, curry dishes, and pickled fish. It is an integral ingredient in Worcestershire sauce. Tamarind can be found in East Indian and some Asian markets in various forms: jars of concentrated pulp, canned paste, whole dried pods.
