I recently came across this recipe on the net.The copy right of the recipe is with http://www.veginspirations.com/search/label/Idli%20varieties
I made one change - that was, in using eno fruit salt instead of baking soda.
The quantity of ingredients used yields 16 medium sized idlis.
Ingredients : 3/4 cup coarsely powdered oats,3/4 cup fine lapsi rava(roasted),1/2 cup raagi ( nachni ) flour,1 tsp eno fruit salt,2 cups dahi & salt to taste.
The dahi & the raagi-oats-rava mixture has to have 1:1 proportion -hence,2 cups dahi as this dry mixture will measure 2 cups.
Seasoning : 2 tbsp oil,1/2 tsp mustard seeds, 1 tsp chana dal,1 tsp urad dal,1 sprig of coriander leaves ( cut finely or whole ),1-2 green chillies( optional )finely cut.
Method: Mix the coarsely powdered oats ,lapsi rava & raagi flour.Add 2 cups dahi & mix thoroughly.Now add salt & eno fruit salt & mix vigorously.Add water if there is need.The mixture must be of idli batter consistency.
Take the 2 tbsp oil in a pan & heat it. Now add mustard seeds.After they splutter add chana dal followed by urad dal.After the dals have changed color slightly,put off gas.Add coriander & green chillies.Add this seasoning to the idli mixture prepared.
Now grease the idli moulds & pour the idli mixture into the moulds.Steam the idlis for 8-10 minutes. Your idlis are ready to be savoured !
This recipe is excellent for diabetics as it has no rice & has raagi & oats.Raagi is a good souce of calcium & oats help in controlling cholestrol.
