Citron pickle, is a flavorful and tangy condiment made from citron, a fruit that is similar to lemon but larger, with a thick, bumpy rind and a strong, tart flavor. The pickle is made by combining chopped or sliced citron with a variety of spices such as mustard seeds, fenugreek, turmeric, red chili powder, and salt. Sometimes, a bit of sugar or jaggery is added to balance the sourness.
