Step 1
Prepare the batter: In a bowl mix suji, curd, salt and water. Mix well to make a smooth batter.
Step 2
Let it rest for 10–15 minutes so the suji absorbs moisture.
Step 3
Divide the batter into 3–4 small bowls depending on how many colours you want.
Step 5
Add spinach puree to one bowl for green.
Step 6
Add beetroot puree to another bowl for pink/red.
Step 7
Add turmeric or carrot puree for yellow.
Step 9
Just before steaming, add baking soda to each bowl and mix gently. The batter will become fluffy.
Step 11
Grease the idli moulds lightly and pour each coloured batter into separate cavities.
Step 12
Steam the idlis for 10–12 minutes on medium heat.
Step 13
Remove and serve hot with sambar and coconut chutney.
