Add 2/3 to ¾ cup water and grind till you get a fine grainy consistency of rice in the batter. a smooth consistency of batter is also fine.
If the mixer gets heated up, then stop and wait for some minutes. when the mixer cools down, grind again. depending on the jar capacity, you can grind everything once or in two batches. i ground in two batches and added overall ¾ cup water.
Now take a ladle full of the batter. pour the dosa batter and gently spread the batter starting from the center and moving outwards.
Fold and serve dosa hot. make all dosai this way.
Serve these crisp dosa plain or with potato masala and coconut chutney.
