Mango is a versatile fruit, as many delicious recipes can be prepared with raw mango as well as ripe mango; such as mango pickle, drinks, mango roll up, sweet or spice chutney, shrikhand, ice cream, lassi, mango kulfi and so on. Sweet & sour mango chutney is one of my childhood favorite, and my mom used to make this dish during mango season in the summer. She would make it in large quantities and store it in a jar. We loved eating it in our lunch boxes with parathas. This mango chutney also known galka or khattmithi in Northern part of India, but every state has its own variation of making this sweet & sour chutney with different ingredients and has many different names. This recipe made with raw mangoes, jaggery and some spices in Eastern UP & Bihar style.
