Combine the ragi, rice flour, yoghurt, and salt in a mixing bowl.
Gradually add the water and other ingredients until the mixture is lump-free and pourable.
Once combined, let the batter rest for a minimum of 30 minutes.
Heat the dosa tawa or griddle and brush a thin layer of oil onto the pan.
Once hot, take one ladle of batter and pour it onto the hot pan, spreading it into a thin circular shape.
Allow to cook until the edges start to roll up off the tawa and the bottom is crispy.
Now, cook the other side of the dosa after flipping it.
Serve hot with fresh coconut chutney.
