Wash and soak urad Dal and Moong dal overnight (or minimum 4hrs).
Drain water and grind Dal into a thick batter. If you find Dal to be too thick, add little water to make it grind easily. Mix it nicely.
Transfer the batter into a large bowl and add salt,black pepper,mint leaves and coriander leaves.
Now add besan and mix well. Stir the mixture nicely to make it airy.Then add fruit salt(eno) and mix it nicely and let it rest for 5 mins.
Now heat water in your regular Idli or dhokla steamer and meanwhile grease your idli plates and keep aside. The batter will start rising, scoop a spoon of batter and place on the greased idli plates. Try to shape them as round dumplings.
Put the idli plates in the steamer and cook for 20 minutes or till the tooth pick inserted comes out clean.
Open the steamer and let take out the idli stand carefully and allow to rest for another 5-6 mins. Now carefully scoop out the steamed vadas and soak them in water for 5 mins.
Meanwhile whisk yogurt and add salt per taste. Line the vadas on a plate and pour thick yogurt all over. Sprinkle roasted cumin powder, red chilli powder, chaat masala and fresh chopped coriander.
Add mint chutney and tamarind chutney for some extra zing .
Serve warm or chilled as per choice. But I prefer chilled dahi bhallas.
