Wash and soak rice for 4 hrs with enough water. Mix both the dals and Fenugreek seeds and soak that too with enough water. Grind the seived rice to a fine paste by adding approximately 1.5 cups of water. Add little water first, do not add all the water together Similarly grind the seived daals too. Now mix both rice and dals,add salt. Keep it covered in a deep vessel for fermenting at least for 8 hrs.

Now prepare the masala.Add oil in a kadai,add the Curry patta, musard seeds, as they split add chopped onions, red chillies,green chillies, turmeric, amchoor powder,salt,add little water so that all the masalas are well cooked. Add in the mashed potatoes, mix nicely check the seasoning add fresh coriander leaves. Keep aside.

Now for dosa,I used a dosa griddle. If you have great else use a non-stick one. The most important thing to remember is to heat the griddle nicely. And then keep the flame low to medium sprinkle some oil spread it and wipe it. Now check the batter if it's too thick add little water so that you are able to spread it. These Dosas are a little stickier as compared to the regular dosas. They take a little more time to cook and leave the sides of griddle. Sprinkle oil & don't be in hurry.

As it leaves the sides, in the center add the masala and wrap half.Usualy dosa are cooked on one side only. So make sure to spread the batter as thin as you can not like chilla which are a little thicker. Serve immediately with your favourite chutney and sambhar!!

Notes
1. I found these Dosas to be crisper than the regular white ones, so I didn't use onion to rub on the griddle before spreading the dosa batter.
2. After each dosa is cooked, sprinkle some water on the griddle and wipe it,then spread the dosa batter.This helps the dosas to come out clean
3. The flame of the gas should be medium and too low or too high. Sprinkle oil to give a shine to your healthy version of Dosas!!
