Then add the rice dough to the urad dough and mix them well, with salt. To make Dosai, Wait at least 12-24 hours to get the dough to be fermented
Heat the dosai tawa, Add the dough and circle the dough and add some oil/ghee to it and close it with a lid.

The Best rice to use for dosai is Ponni Idli rice and the white Urud dal .you can make the dough in the mixer, the taste of the dosai will not change much but the idli would not be the same when the flour is ground using the mixer. You have to soak the rice and dal for about 5 - 12 hours and has to be ground separately each about 5-6 minutes in a mixer , about 20 minutes each in a grinder, but the time may vary depending on the mixer and the grinder you use, just keep feeling the flour , make sure that the flour is well ground.
