Whenever I have some leftover Idly/Dosa batter..My choice is this rava dosa only..Yes I add the leftover batter to make rava dosai.I heard people using a buttermilk to make rava dosai this is an alternate way..I usally add some grated carrots to give it a nice color..I also add some cashews for some rich taste..if you have this rava dosa with sambar you feel like heaven..
3.leftover batter-1 cup
5.onion-1 (finely chopped)
6.green chillie-3-4(finely chopped)
7.curry leaves-1 stalk
8.pepper seeds-1/2 tsp
12.cilatro - 2 tbsp (finely chopped)
1.Mix the rava,left over idly batter,rice flour and salt in a big bowl with enough water.(make sure it should be very watery).
2.In a skillet add oil when it is hot add the pepper seeds ,zeera when it started spluttering add the curry leaves and cashews.
3.add the onion,ginger,green chilli,when it is fully cooked add it to the batter.
4.add the grated carrot and cilantro to the batter.
5.Mix it nicely if needed add extra water.
6.In a heated dosa tava pour the batter on the outer side first,it automatically fills the inner side of the dava ..due to the very watery consistency..add oil to it and when its done flap the dosa carefully and cook the other side..
7,Do the same with the remaining batter..
8.Serve hot with chutney and sambar..
