Tamarind paste is made from a sour, dark, sticky fruit that grows in a pod on a tamarind tree. While some cuisines use tamarind paste to make desserts and even candy, in Thai cooking it is used mostly in savory dishes. Classic pad thai sauce is made with tamarind, as are some Thai curries and seafood dishes. Indian curries also call for tamarind. It is also a common ingredient in Indian and Mexican cuisines, as well as Vietnamese, Latin, and Caribbean cooking. It is also a key ingredient in Worcestershire sauce, contributing to the distinctive tang.
