I used the rice cooker cup for this recipe.
1 cup = 160 ml
idli rice = 3 cups
urad dal=1 cup
fenugreek seeds/ vendhayam = 2 to 3 tbsps

  • Wash and soak all the ingredients together in water for a minimum of 5 hours. I usually soak it overnight.
  • Drain the water and grind it in a wet grinder or even your blender in batches, adding small amounts of water at regular intervals. 
  • The end batter will have a coarse texture.(slightly grainy to the touch)
  • Add enough water to blend to have a slightly thicker batter.
  • Pour it in a big container, mix well and leave it to ferment in a warm place. About 6 to 8 hours.
  • Once it has fermented (the batter would have risen) you can put it in the fridge
  • To make dosas, take required amount of batter in a bowl, add salt and water and mix. Batter should be of pouring consistency.
  •  For more keeping time in the refrigerator, do not mix salt to the entire batter. Mix only as and when you need.
