Follow the same procedure for Dosa Batter and Errakaram as I have explained in Masala Dosa recipe.
Heat the pan and when it is hot enough, spread the dosa batter and immediately break an egg and spread it accross using spatula or fork as shown below

Drizzle some oil. When it gets fried turn to other side and allow the egg to cook for a minute. Now turn the dosa back and apply Errakaram and serve hot.
