Clean and soak rice in water for 6-8 hrs. Have the grated coconut ready.
There are two ways to make this batter. Either you can grind the grated coconut along with the soaked rice or you can add this after grinding the rice to a smooth batter.
If you add the grated coconut directly, it will be little difficult to spread it as a dosa. But you get to munch on the coconut.
When its ground along with rice, you get a smooth batter, which is easy to spread as a dosa.
Once the batter is ready, you can immediately make the dosas as this does not require fermentation.
Heat the tawa and grease with oil. Pour a ladle full of batter in a circular way and join it to make a even spread pancake.
If the batter is really smooth, it can be spread as a regular dosa too. Sprinkle oil, sim for a while and flip to the other side and cook well.
Serve this with Onion chutney.
