Amchur powder, also called dry mango powder, is a spice made from dried, unripe green mangoes that have been ground into a fine powder. It is often used in Indian cuisine to add a tangy, sour flavour to dishes. To make amchur powder, unripe mangoes are peeled, sliced and then dried. The dried slices are then ground into a fine powder. The resulting powder has a light beige colour and a sour taste, with hints of citrus and astringency. Amchur powder is often used as a seasoning in dishes such as chutneys, marinades, and curries. It can also be used as a substitute for lime in recipes that call for a sour element. It is also often used as a tenderiser for meat.
