Masala Dosa

Soak in water for at least 6 hours. 
     1 cup Black gram dhal (urad dhal)
     2 cups idli rice, sona masuri rice recommended but any other rice works as well.
     1/4 cup chana dhal, 1/2 tsp methi seeds
Soak in the afternoon, grind in the evening and ferment overnight for making dosas for next morning's breakfast.

Wash and grind all of the above to a smooth paste with water used for soaking. The batter should pouring consistency to roll on the griddle (slightly thinner than a pancake batter, thicker than a crepe batter)

Ferment overnight in a warm place. There are two options for fermenting in cold countries - 1) Turn oven on to 150 degrees, then turn it off and after a few min put the batter in there (make sure the vessel is big, as when fermented the batter doubles in volume). 2) If you own a Instapot with yoghurt setting, that works wonders....just put the batter in the pot and press yoghurt.

Next morning, add salt to taste and 1 tsp. cumin seeds to the batter and mix well.
