For the batter, all the dry ingredients- Besan ( chickpea lentil Flour), rice flour, salt, red chilli powder, carom seeds and cumin powder.
Add water, a little at a time, and make a smooth batter. Use a whisker or a fork to remove the lumps, if any. The batter should neither be too thick nor too thin.
Add baking soda just before you are ready to fry.
Dip the chillies, one by one, into the batter. Coat them well and fry them in medium hot oil.
Once fried, cut them into pieces.
Garnish with finely chopped onions and coriander leaves. Squeeze lemon juice and sprinkle black salt and serve.
