Grease a steel plate and pour a small ladle of the beetroot puree first. Over it a ladle of the white idli batter.
keep pouring the batter alternatively. With a toothpick, draw lines from the middle to the edge or vice versa thus forming a beautiful pattern.
Steam for 13-15 minutes. When it cools down, run a knife around the edges to loosen it and gently demould it . Pack for your kid's lunch box meal with coconut chutney or idli podi sprinkled over it. A nice way to feed your kids some healthy stuff.
