Dip the spinach leaves in boiling water for 2 mins. Wash under cold running water. Grind to a smooth paste alongwith the chilles and garlic.
In a bowl, combine the rest of the ingredients alongwith the palak paste to make a smooth batter of dropping consistency. Add water as needed. Set aside for 30 mins.
In a non-stick pan, put a few drops of oil. When hot put a spoonful of batter and spread it with the back of the spoon to make a thin round. When done on one side, flip over and brown the other side.
Serve hot with green coriander chutney - coriander, green chillies, garlic, one tomato, salt - all chopped together.
