1.Clean, wash and soak the ragi grain, black gram and rice for around 4 hours.
2.Strain the water and make a smooth batter by grinding all the grains.
3.Take out the mixture in a bowl. Mix the batter thoroughly. Add salt and mix well.
4.Allow the batter to ferment for at least 4 hours or overnight during the winter season.
5.Once the batter is fermented, give it a good stir. (If it's too thick, you can add a little
water to adjust the consistency)
6.Grease the idli mould with oil and pour the batter into the moulds.
7.Steam the idlis in a steamer for about 10-15 minutes or until a toothpick inserted in
the centre comes out clean.
8.Once done, let the idlis cool slightly before removing them from the moulds.
9.Serve hot with coconut chutney and sambar.
