*Soak 2 cups whole moong dhal with 1/2 cup rice for 5-6 hours. Usually I soak this in the morning before I go to work. I tried with 1/4 cup rice but it did not come out crisp. We usually like crisp dosa and in some recipes online they mentioned to add rice flour. When I tried that method it did not taste good.

* Evening after I come from work I grind this mixture into a nice batter consistency. All recipes online ask you to grind onions,ginger and green chillie along with soaked moong dhall and rice, when I did that my kids did not like it as it was spicy.So I grind (green chillie+ginger )mixture (sometimes I will add coriander leaves or kothamalli for extra flavor) separately by adding some water and will keep it aside.
*On a griddle spread the batter similar to how you make dosa and sprinkle some onions and oil.
