Tamarind

The fruit of a tropical tree, tamarind is an indispensible spice in most south Indian kitchens. Today, India is the only producer of tamarind on a commercial scale. A large part of India's production of tamarind is exported to West Asia, Europe and America, where it is used in such food specialities like Worcestershire sauce. 

This spice also comes in the forms of pulp and juice concentrates which mainly go into the preparation of cool drinks, seafoods and a range of sophisticated cuisine.
