Wash the eggplants and cut into thin slices.
Heat oil in a non-stick pan on a high flame. Once hot, lower the flame to medium.
In a large bowl, add besan, rice flour, kalonji, red chilli powder, sugar, salt and baking soda. Mix it well.
Gradually add water and make a thick batter. Add 1 tsp hot oil to the batter and whisk it well.
Dip the begun/baigan into the batter and coat both sides well. Carefully slide them into the oil and fry until golden brown.
Transfer the beguni/eggplant fritters to a plate lined with absorbent paper. Serve them hot with khichdi.
