In a bowl mix rava, rice flour, maida and curd. Add the jeera, asafoetida, chopped onions, methi leaves, green chillies and grated coconut. Add some water so that the batter is thick and of dosa consistency. Add salt according to the taste. Keep it for 30-40 minutes.On a medium flame heat a non stick tawa with few drops of oil. Pour 2 table spoon of batter and spread it a little. When the dosa becomes crisp and red, turn it and cook the other side for few seconds. Serve hot with Coconut Chutney and Butter/Ghee. This dosa tastes very good.
