Allow the fried mixture to cool. It should not be hot.
First grind the red chilly, split Bengal gram in a mixie (dry grinding, water should not be added).
Now add the coconut to it and grind it, again dry grinding only.
Now add the prepared mixture and grind all the ingredients together to a paste.
