I have not tried it yet. I will be trying it very soon. Must be good my mother never enters anything not tasty.
First take semiya and soak it in buttermilk for one hour.
After one hour smash the semiya and make it smooth now add flour and onion and chili pieces and also add salt and mix well.
The consistency of the batter should be loose and runny.
Take a pan apply oil and when heated take big laddle full of batter and pour it from out side forming a round dosa. you need practice, Leave oil around the dosa and when fried turn it and fry it on the other side also. Serve hot with chutney.
