While those white idlis are a common sight and need ahead of preparation time for soaking and fermenting, rava idli is a quick fix in comparison. With the addition of veggies like peas, tomato, it's nutritious as well as filling.
1/4 tsp - Eno fruit salt
2 ) Now transfer to a plate and cool. Once rawa has cooled down,then do the next step. In a mixing bowl add curds and beat well.Then add green peas, tomato, coconut and salt to taste. Dissolve hing powder in little water and add to the batter. Then add cooking soda and eno to the batter and stir in well. Then add roasted rawa and mix well. The batter consistency should be like the idli batter ( add little water if the batter is too thick). Immediately go ahead and make the idli's.
Note - If the curds/ yogurt is sour then don't add tomato. End result could be too sour idli. Use yogurt that is not sour for this recipe.
