Parboiled rice (Idli rice) - 2 cups
Urad daal - 1 cup
Methi seeds 1 spoon
Salt to taste
Oats - 1 cup
Soak Rice and urad daal + methi separately for 6-8 hours. Just 15 minutes before grinding it, soak the oats in just enough water to cover it. Grind the urad daal + methi first till you get a fluffy batter. Remove it from the grinder / mixer. Add rice and the soaked oats and add enough water and grind it well. Mix this with urad daal batter and add salt and mix well. The batter should not be too thin. It should be little thick. Let it ferment overnight.
Apply few drops of oil in the idli moulds and steam it for 15-20 mins in the idli cooker.
To check whether it is done, insert a fork. It should come out clean.
Note : Depending on the brand of rice and urad daal use the quantity may differ. Use the rice and oats in 3:1 proportion. After couple of days, you can use the same batter to make dosas and with added oats you get golden brown, crisp dosas To make dosas, add little water to the batter to make it slightly . I forgot to take pictures of the dosa.
