Rinse and soak the urid dal and the quinoa separately. Add the methi seeds to the urad dal to soak. Soak for a minimum of 5 hours.
Soak the idli rava/sooji in a deep vessel. Let it stand for a few minutes. Then decant the liquid. Repeat for 2-3 times. Set aside after the last rinse.
Drain the urid dal and reserve the water.
Grind the urid dal and methi using the mixer in pulse mode initially till the dal moves smoothly adding water little by little. I must have used about ¼ to ½ cup for the grinding.
Then I use the buttons from 1 to 3 to get my smooth paste. Add the urid dal mixture to the Idli rava/sooji vessel.
Grind quinoa to a smooth paste add water if needed. Remove the batter into rava/sooji vessel.
Mix all the contents well. The consistency of the batter should be like our regular idli batter and should not be too thick or too thin. You can add salt if you wish I add it just before making the idli.
Leave the batter to ferment for 6 hours or as in my case overnight.
Just before making the idlis I add my salt and mix well.
