Every day we discover something new in the markets! We often use tamarind when we cook, but we had never come across it fresh! Whole tamarind pods are categorized depending on the stage at which they were harvested. Sour tamarind, or green, unripe tamarind, is the most tart and acidic. Ripe tamarind is brown, with a pleasantly strong sour taste. Sweet tamarind can be eaten straight from the pod. Fresh pods can be found at Asian and Indian grocers, and often at your local independent greengrocer.
