Amchur is made from unripe sun dried mangoes, which come in whole or powdered form. This spice is used in many Indian cuisines. Amchur is similar to lemons in flavor, but a bit milder, it adds a tart, sour taste to dishes.
Uses:
Usually found in Indian cuisine, used in curries, fish dishes, chutneys and marinades (amchur has tenderizing qualities similar to lemon and lime).
Storage:
Store amchur in airtight containers in a cool dark place. Never store in the refrigerator.
Substitutions:
You can substitute lemon or lime if you don't have amchur handy. 3 Tbsp lemon/lime juice for 1 tsp amchur.
