Measure each ingredient as per the above measurement and keep seperately.
Soak rice, urad dal with fenugreek seeds in water each seperately for atleast 2 to 3 hours.
Then drain water from urad dhal+fenugreek seeds and add it to the grinder.
While adding urad dhal take care the grinder doesnt get stuck. Sprinkle water then and there and grind it for 40mins in total.
Its always better to stand near atleast during the final stage of till the proper consistency is reached.
Keep sprinkling water in between at regular intervals. The batter should be light and nice fluffy.
Collect the urad dhal batter in a container(big enough to hold the fermented batter).
Now drain water from rice and add it to the grinder, sprinkle little water and start grinding.
Grind it for 30mins on the whole, keep adding water in between.
Grind it smoothly with a slight coarse texture. The rice batter should be slightly thicker than urad dhal batter.
Now take the rice batter and urad dhal batter, add salt and mix well.
Keep aside in a warm place to ferment well for atleast 10 – 12 hours.
Can you see the fermented batter with a porous look? If you see the batter would have raised well and now your idli dosa batter is ready to use.
Take a laddle full and add it to the idly pan and steam it for 10-12mins.
Sprinkle little water and carefully slide around the edges to take the idlis.
Hot soft idlis ready to be served.
