Heat a non-stick tawa / griddle and grease with a little oil. Sprinkle some water and after it sizzles off, wipe dry with a clean cloth / kitchen towel.
Now pour a ladleful of the batter and spread it in a circular motion. Drizzle some oil over it and around the edges. Cook for a minute on one side.
Then sprinkle some podi all over the dosa and 1 tsp. of oil. Fry for a minute more and then transfer to a serving plate.
Make similar podi dosa with the remaining batter and relish with coconut chutney and sambar.
