Heat a tava and grease it with a little oil. Mix the dosa batter again, take a big ladleful of batter and pour it over the heated tava in circular motion to form a round dosa. Sprinkle oil over the edges of the dosa. When the edges turns crispy, lift the dosa and roast it on the other side. Turn the dosa again and sprinkle the fried mixture on top of it.
