Wash and soak the sago pearls in water just enough to cover the pearls for 20 minutes. After 20 minutes, drain the excess water if any and cover the pearls for 3-4 hours or preferably overnight. The sago pearls should be non-sticky and soft before making the khichdi.
In a non-stick pan, heat ghee and crackle cumin seeds.
Once the seeds crackle, add the boiled and chopped potato and carrot and stir fry for 1-2 minutes.
Now add the soaked sago pearls and stir fry for 2 minutes.
Add warm water to the khichdi and cover. Let it cook until done.
Add chopped coriander leaves and black pepper powder and mix well.
Turn off the flame. Add lime juice if desired. Serve the sabudana khichdi warm with some curd to your baby.
