Blend the rice, dhals, red chilli, ginger and cumin seeds togeather in a mixer to a coarse paste by adding little water.Set aside.
Add onion, coriander leaves, curry leaves, salt and hing and mix well.
The batter should be thicker than idli dosa batter. So you can adjust water as needed.
Heat the dosa tawa or normal tawa/griddle, take one laddle full and spread the batter like we do for dosa.
Drizzle little oil and once it is cooked turn to other side and cook until golden brown.
Serve hot and enjoy along with a cup of tea.
This can be served along with coconut chutney, tomato sauce, curd, pickle etc...
