Raw rice                               : 1 cup

Kappa(tapioca)                    : 200gms

Grated coconut                    : 1/2 cup

Salt to taste

Coconut oil                         : 1/4 cup

Soak the rice for 30 mins. Peel and wash the tapioca well and cut into small pieces.

Grind the rice with tapioca pieces and grated coconut into a smooth paste. Add enough water to make a thin batter. Add salt to this and mix well.

Heat the dosa tawa and pour one full ladle of the batter in the middle and just swirl the the tawa to spread the batter around  to make a thin dosa. Sprinkle little oil over the edges of the dosa. 

Let it cook for one minute and flip it over to cook the other side.

Remove from the tawa . Now the tapioca dosa is ready to serve. Serve it with onion  chutney(Ulli Chammanthi).
