Wash urad dal and rice . In a bowl take rice,urad daal,methi and sabudana and soak in enough water for around 5-6 hours.

In another bowl soak poha with fresh curd for about 1-2 hours .

Drain water from the soaked daal rice mixture . Transfer them to a mixer or grinder along with poha soaked in curd . Grind all to make a smooth batter adding little water .Dont add much water while grinding.

Add salt to the batter , mix and allow to ferment overnight or 4-6 hours. The batter has to be thick at this stage. As it ferments , it will get thinner .

In the morning / after 4-6 hours , you will observe that the batter has fermented nicely . Add soda and sugar to the batter and mix gently . Check the consistency of the batter . It should be thick milkshake consistency . If required add little water . Our set dosa batter is ready .

Lets proceed to make set dosas. Heat a tawa. Grease with little oil.Pour a laddle full of batter. No need to spread. It has to be like thick small pancakes .

Drizzle few drops of oil around it.Cover and cook on medium flame for abt 1-2 mins.Once its done, the dosas comes out easily from the tawa .If you want you can flip and cook other side too for about 30 sec or serve as such.

Super soft ,porous and spongy Set Dosa is ready. Serve hot with chutney / veg saagu / veg kurma / potato saagu / sambar / chutney powder .
