Crack open the pod by pulling the dry connective thread that runs the entire length of the pod.
Scoop out the flesh and the seeds and place them in a small saucepan. Cover the seeds and meat with water. Add just enough water to cover them. Too much water will lessen the strength of your seasoning. One tbsp. tamarind to 1/4 cup water is a good ratio.
Turn the heat on a low temperature. Cook the tamarind for 3 to 5 minutes, just to make the tamarind mushy. Allow the mix to cool.
Pour the saucepan contents into a sieve placed over a glass bowl. Push the remnants in the sieve down, squeezing out any remaining juice in the flesh and seeds. Throw away the sieve contents.
Pour the thick liquid left behind into a plastic container with a lid. Refrigerate the tamarind until you are ready to use it. Tamarind will keep refrigerated for up to one week.
