Wash and soak the rice, urad dal & methi seeds together for two hours. Add the required water and grind everything all together adding required salt & water. Lastly add the ragi flour, grind for few minutes. Remove and ferment overnight or 10 hours.
The next day, batter would be doubled and sometimes overflown too. Stir well and make idlies.
Steam in idli mould for 10-12 minutes till the inserted spoon comes out clean.
U can make dosas by diluting the batter slightly. Make crispy or soft dosas as per ur need.
Enjoy with chutney, sambar !
Notes
For variations, you can use whole ragi grains instead of flour.
If you want to try without rice, use 3: 1 ratio of ragi flour and urad dal. Add 2 tbsp of poha for softness.
While making dosas, you can temper and saute onions, green chillies, ginger & curry leaves as it makes the dosa flavourful.
