Introduction: What Is Tamarind


Tamarind is a hardwood tree originating in Africa, and probably brought to the Indian subcontinent by Arab merchants. Its biological name is Tamarindus indica.

The tamarind plant produces brown pods containing some large seeds and a delicious pulp. Tamarind pods are irregularly shaped, curved beans, somewhat similar to carob. When the fruit is not mature, the pulp is green and the seeds white. As tamarind pods mature, the pulp becomes brown, sometimes with a touch of red, and more sticky in consistency. The pulp is the most used product of the tamarind tree, especially for cooking. The leaves are also sometimes used in Indian cuisine, while oil can be extracted from its seeds.
