Take boiled rice in a bowl and rinse in water twice or thrice and then soak it in water. Take urad dal and fenugreek seeds in another vessel and rinse it in water twice and add water to soak them.l
Add generous water to the dals and rice as the soaking process makes them double their size.

After 4 hours, drain the water from uraddal and add it to the grinder. Initially add 1/2 cup of water to the grinder and start the grinding process.  Then slowly sprinkle water in regular intervals and grind the urad dal to a nice and thick batter. This process usually takes at least 20 minutes. If the urdal quality is good, then we would get more batter. After 20 minutes, our urad dal batter is nice and smooth and if we take some batter and roll it in our hand it should roll like a soft ball.

Mix both the batters well with a ladle or clean hand. Add 4 tablespoon salt and give a nice mix then close the bowl with a air tight lid or a proper lid to cover the bowl completely and keep it aside for 12 hours or overnight for fermentation.

After 12 hours, we could see batter has fermented and the quantity would have doubled up. Our Idli / Dosa Batter is now ready for making Idlis / Dosas
