The simplest way to enjoy tamarind is in the pod form. Break off the brown outer pod and remove the stringy part that looks like a small root wrapped around the pulp. You will be left with a long piece of pulp that has rock hard seeds inside the size of large corn niblets. Cut it into sections and eat, nibble around the seeds and spit them out. Keep in mind too much tamarind can have a laxative effect.
