HalfPint is a trusted home cook.
Asian grocery stores, Chinese, Vietnamese/Thai, or Indian to be more specific. Korean and Japanese do not tend to cook with tamarind. If don't have these stores nearby, then check out Amazon or any online outlet.
The Whole Foods near me sells the tamarind concentrate if you have a WF near you. Its in a little yellow tub with a red lid.
It's easy, peasy.
