To make idli:- soak idli rava, urad dal and fenugreek seeds separately for about five hours. After five hours by adding a little water to it, grind the soaked urad dal and fenugreek in a mixer to a fine paste. Now add idli rava to it and grind it coarsely. Mix everything together with a spoon. Cover the bowl and leave the batter to rise. After seven to eight hours, the batter will rise. Then add salt to taste and mix it well.

Divide the idli batter into three parts.
Add spinach puree to one part and carrot puree to the other. Keep one part white as it is.

After fifteen minutes, remove the idlis and let them cool. Now heat oil in a pan and add asafoetida, cumin seeds, mustard seeds, curry leaves and let it crackle. Add the prepared idlis, stir lightly and immediately turn off the heat.
