Soak dal and rice separetely for 2 hrs. After 2 hrs. wash it properly.Then grind dal and rice separetely. Once it is done.

Transfer to a bowl. Keep for fermentation over night. Next day how much batter you want. Transfer to a bowl. Add salt as needed. Mix it well.

I always use iron tawa. First heat iron tawa in a high flame. In a small bowl take oil and in another bowl take water. Cut the edges of the onion. Wash it well. Dip the onion in a oil.

Slow the flame and brush oil in a iron tawa then brush water wipe it. Add dosa batter. Spread it evenly and cook in a slow flame till it is light brown and colour both the sides. Once it is done. Then transfer to a serving plate.
