Dried mango powder is the souring agent of choice for vegetarian preparations, including lentils. When the fruit is in season, small pieces of unripe, tart mangoes are cut and cooked along with arhar dal, or in vegetables. But when the season gets over, it is amchoor that takes over. Amchoor powder has several uses in the culinary world. It is used to add more flavour to curries, chutneys, soups and marinades. The dried slices add more taste to the dishes. It has tenderizing qualities, similar to lime and lemon juice.
