This mixture divide in big lemon sized balls. These balls flattened by both palms like bade. Heat oil in a kadai and deep fry these bade on high flame until they becomes golden brown and crispy on both sides. Only 3 or 4 bade deep fry once in a time in very hot oil. Serve hot with any chutney or fresh curd in upvas.
