in a mixing bowl, combine rava, rice flour, all maida (1:1:½) and cumin seeds, salt.
mix the ingredients with a cup of water. make sure there are no lumps formed.
add finely chopped onion, coriander leaves, curry leaves and chilli.
add more water to adjust the consistency of the batter. it should be watery like neer dosa batter. else the dosa will not be crisp. keep aside for 30 minutes.
heat the tava or non-stick pan and spread 1 or 2 tsp oil. if using non-stick pan then no need to spread oil.
pour batter from the edges towards the center.
sprinkle ½ or 1 tsp of oil from the top.
let the base turn crispy golden. keep on medium flame to cook.
serve the dosa. no need to roast on other side.
rava dosa has to be served immediately with coconut chutney.
