Did you know Rava Idlis were first invented at MTR? During World War II, rice was in short supply. MTR experimented with wheat and thus was born the enormously popular "Rava Idli."   Serve with coconut chutney and potato sagu.   Mix 1 measure of mix with 1/2 measure of sour curd.   Add 50g of finely chopped coriander leaves to the mix.     After 1 min, add 1 measure more of sour curd and mix well.   After 2 min, steam batter in an idli cooker or idli vessel for 10-12 min.
