In a bowl, take 4 cups Ragi flour. Add 1/2 tablespoon salt and mix well. Now, add 3 cups water in installment and mix well so there are no lumps.
In a pan, heat the oil and add chana dal, urad dal, mustard seeds, and curry leaves.
Once the seeds splutter, add the chopped onions and fry well until the onions become translucent, while adding about 1/2 tablespoon salt.
Let this cool.
In the ragi batter, add rava, and the tempered onion. Add another 1/2 cup water, 1 tablespoon salt and mix well.
The batter should be runny. Let the batter sit for at least 10 mins.
Now make the dosa as you would make rava dosa – just be a little liberal with the oil.
Refer to the video for making dosas, if in doubt.
Serve the crispy, yummy ragi rava dosa with coconut chutney!
