Heat the dosa tawa/griddle and pour the batter in the center of the tawa and spread it from inside out.
Drizzle little oil around the corners.
After a minute, flip the dosa and remove from heat after half a minute.
Serve immediately with sambar/chutney/milagai Podi.
I served mine with onion chutney and coconut-coriander chutney.
Refrigerate the remaining batter in an airtight container.
