Wash and soak 1 cup whole skinned urad dal and 3 cups barnyard millet separately in plenty of water. Set aside for a minimum of 4 hours up to 8 hours
If using, add 1/2 tsp fenugreek seeds to the urad dal while soaking
Grind the urad dal first, adding enough water to make a thick and smooth batter that's slightly thick and fluffy
When done, remove into a large bowl and grind the soaked millets. Take care adding water at this stage because the millets soak up water and release when grinding. It's easy to have your batter get too watery at this stage so take care
Add 3 tbsp poha at this stage with the millets, if using
Remove and add to the same bowl with the ground urad dal
Add 1 tbsp salt and give everything a really good mix. Using your hands to mix makes the batter ferment better, apparently. Do what works!
Set aside in a warm place to ferment for 8 hours or overnight. The batter will rise a bit and turn bubbly.
To prepare dosas, heat a griddle and grease with gingelly oil
Pour about 1/4 cup of batter and make into thin rounds.
Add more oil and flip when the first side is cooked
Cook the other size until crisp and done.
Transfer to a plate and serve with sambar and chutney for a nutritious and fillng breakfast or dinner
