Idli (how to make batter?)

3 cups Boiled rice
1 cup Urad dal
1 tsp Fenugeek seeds

Steps
1) Soak the rice overnight.
2) Soak the Feengeek seeds in a separate vessel overnight. (Do not throw the water and use it while grinding)
3) Soak Urad dal an hour before grinding.
4) First grind the Urad dal. Take 1/2 tsp of the batter and drop it on a cup of water and it should float. Grind until the urad dal batter reaches this consistency. It usually takes 5 - 8 minutes. Add water as required.
5) Remove the Urad dal batter from the grinder/food processor and keep it aside. Now put the rice and fenugeek seeds to grind.
6) Rice batter need not be of smooth consistency, transfer to the ural dal batter and mix it well.
7) I usually add salt and little bit of curd so that it cultivates yeast. If you are in hot weather this will not be required.
