Combine maida, rice flour, rava, salt in a bowl.
Add water and make a very thin batter. The consistency of the batter should be like buttermilk.
Add black pepper, curry leaves and coriander leaves. Mix nicely and set batter aside.
It is best to rest the batter for 10 - 15 minutes.
Heat a non stick dosa pan over high heat.
Pour one or two ladleful of batter on the pan so that it forms like a web with big holes.
Do not spread the batter like regular dosa. Simply pour it over the pan.
Drizzle a teaspoon or so of ghee/oil on the sides of the dosa. Do not flip the dosa.
Let the dosa turn crisp and golden from one side. Once done, it's edges would leave the pan.
Flip the dosa and cook fro 1 - 2 minute from the other side.
Fold and serve instant rava dosa immediately.
