|It is very simple and easy to prepare it. First of all, you are required to heat about two tablespoons of oil. Add mustard seeds and when the seeds start to crackle, add the cumin seeds, green chili, salt, ginger and garlic. Fry for a few seconds and add onions and turmeric powder. When the onions start to turn brown add coriander and lemon juice and the potatoes. Mix well and turn off the heat. Let this mixture cool. Shape into small balls. Next make a thick batter with Besan/Chickpea flour, salt, red chili powder, baking soda and water. In a frying vessel, heat the oil. Dip the potato balls into the batter and carefully drop in the oil. Fry them till they turn golden brown. Serve them hot with tamarind or green chutney.
