Thanks for the link Bob.
I need to formulate a recipe for a beer that contains Tamarind as I assume the OP does. In the Philly area they have a home brew competition where they provide a secret ingredient, which was given out yesterday. It is called sweet tamarind and looks like it is a paste form.
I like the american wild idea, or I am thinking lighter beers to make sure the tamarind stands out, as that is a requirement. There seem to be some traditional tamarind pairings that also can frequently be found in beer.
