Preparing the Masala Dosa
Heat a flat pan or a flat non-stick pan. Smear some oil if using an iron pan or griddle. don't smear oil on a non stick pan, as then you won't be able to spread the dosa batter.
Spread the dosa batter in a circular way on the pan. Add some oil on top
Flip and cook the other side. Flip again.
Spread the potato sabzi filling on one side of the dosa.
Cover with the other half and let the dosa cook for 15-30 seconds.
Serve masala dosa hot with coconut chutney and sambar
- If you are unable to spread the batter on the pan, then add some water to the dosa batter. this will help you in spreading the batter evenly on the pan.
- To get golden brown dosa, the pan should be hot. But the flip side is that if the pan is very hot, then you cannot spread the dosa batter nicely. Either sprinkle water on the pan and then wipe it. This brings down the temperature of the pan. Do this method on an iron pan. Don't do this on a non stick pan. It might affect the non stick coating.
- If using a non stick pan than as soon as one dosa is done, reduce the flame. Spread the dosa batter on the pan. now increase the flame and let the dosa cook.
