Step 1: grease a pan with little oil. Add mustard seeds, cashew nuts(cut into half), curry leaves. Add rava (around 1 small tumbler). Cook for a few minutes while stirring.
Step2: allow the mixture to cool
Step 3: now add fermented dahi to the rava mixture. Mix thoroughly till you achieve proper consistency to make idlis. Add salt, mint, coriander leaves and mix well. Keep aside for five minutes.
Step4: divide the above rava and dahi mixture into four parts.
Part 1: add finely ground tomato and mix well. This gives you red idlis.
Part 2: add blanched and finely ground spinach leaves and mix well. This will give you green idlis.
Part 3: add little turmeric powder. This will give you yellow idlis.
Part 4: keep it as it is to give you white idlis.
Step 5: steam the idlis for 10-12 minutes.
Step 6: allow a few minutes standing time
Serve along with coconut chutney or mint coriander chutney and/or sambar.
1) one medium sized tumbler rava should give you three to
four idlis of each color.
2) you may chose to add finely chopped vegetables like carrot, beans or even peas in step 2
3) in addition to children, the colorful dahi rava idlis serve as a healthy and tasty snack/ breakfast to the diabetic elderly at home too!
So make your breakfast colorful and enjoy!! :)
