Wash rice and dal well in lots of water. Soak them overnight. Drain them and set aside.
Now Take the soaked dal and rice in a blender, add rice flour and puree them. Add in water and blend them till they are well blended.
Pour this in a bowl and add in salt. Add some water if needed and mix well. The batter shouldn't be too thick or too thin.
Now heat a tawa, pour a ladleful of batter in and make thin dosa. Drizzle some ghee or oil around the sides and cook on medium heat till it is golden.
Fold and serve.
Notes
Wash rice and dal very well and then soak them.
While blending, the rice wont get too smooth. If it is a little grainy it is not a issue, But the dal should be too smooth.
I used store bought rice flour for the dosa and it worked perfectly.
In this dosa, since there is no fermenting, the consistency of the batter is very important. You should make it little pouring consistency, not too thick or too thin like rava dosa.
Cook it on medium heat till it gets nice colour on the dosa.
You can store this batter in fridge for two to three days.
This dosa is best when made thin, don't make it thick.
If you see that the batter is not spreading properly, then add little water to it. The consistency is the problem.
Serve this dosa with sambar, coconut chutney or tomato chutney.
