Dosa Batter - as required
Red Onions - 1 or 2, medium (OR) Shallots, chopped
Dried Red Chillies - 4 to 5, broked into small bits
Idli Milagai podi - to taste
Mustard seeds - 1/2 tsp
Oil - 2 tsp + enough to make dosas
Salt - to taste
1) Heat the 2 tsp of oil in the karahi and toss in the mustard seeds, once they splutter, add the broken bits of dried red chillies and the chopped onions with some salt. Cook until the onions brown. Set this mixture aside.
2) Return the karahi to the stove and add a spoonful of oil and swirl it a little bit. Pour about one to two scoops of dosa batter and spread it just a little bit in the bottom of the pan. Sprinkle the idli milagai podi and onion-chilli mixture on top. Drizzle some oil along the edges and on the dosa.
3) Let this cook on a low flame and when the bottom is fully cooked, turn it over and cook the other side as well. It tastes good all by itself and doesn't really require any other accompaniment.
