Sponge dosa

4 cups rice

½ cup sabudana
½ cup urad dal
1 cup poha
¼ tsp methi seeds
Salt
Baking soda

Soak all the above separately for atleast 6 hrs.

Now grind them all into a fine paste. First grind urad dal+methi seeds, then add the sabudana into it and grind, then poha (without water). Lastly, the rice. Pour into a larger vessel. Add salt and adjust the water consistency. Leave it overnight for fermenting.

Heat non stick pan, pour a ladle of the batter. Turn the pan to spread the batter and cover it to cook. Flip to other side and cook that side too. Serve with any chutney.
