1. 2 cups Semolina, Sooji
2. 1/2 cup Rice flour
3. 1/2 cup Ragi flour
4. 1 cup Yoghurt
5. 1 cup Water
6. 1 Large onion, chopped
7. 2-3 green chilies, chopped small
8. Handful of curry leaves, chopped
9. A pinch of Asafoetida
10. Salt to taste
11. 1 tsp Baking Soda
12. Oil for shallow fry
13. 1 tbsp Ginger paste
Mix everything together and keep aside for atleast 1 hour. Stir and adjust water to make medium consistency batter.
Grease a non stick Tawa with oil. Pour a spoonful of batter in the center of the griddle. Spread it in oval or round shape. Drizzle some oil around the edges ( that will work for the first batch, after 2-3 dosas you dont need to pour in more oil )
Cook for 2-3 min till it gets crisp and golden in colour.
Remove from the flame, stuff with potato filling or enjoy with Chutney..
