This Tamarind BBQ Sauce is in the sticky, goey tradition of finger-lickin', (not the St. Loius-style spice rub type) but with a very unique twist. Tamarind is derived from the seed pod of a tree that is commonly harvested from the Carribbean and Thailand. The ripened pods are sticky and goey themselves, with a texture much like marmalade right from the tree. Prepared tamarind sauces and tamarind paste are readily available, but creating the paste right from the pods is easy. Simply cover with double the quantity of water and simmer for a few hours allowing the liquid to reduce by half. The push the contents thru a mess strainer, much the way one would do when making jam.
