Tamarinds are an interesting delicacy that is used around the world and can be found in Zanzibar. This is a huge evergreen tree that produces large bean-like pods with a fibrous pulp filled with seeds. It is not necessary to eat the green bean because they are still sour. The ripe fruit is much sweeter, though with a bit of sourness too. Inside, the Tamarind's pulp is like a paste. Some chefs add it as a component to the famous Worcestershire sauce. The maturing of Tamarind in Zanzibar lasts from late spring to early summer. After harvesting, you should store them in a refrigerator.
