Ingredients 

•  2 cup Sago 
• 2 cup buttermilk 
• 1 onion
• 4 green chillies.
• 2 tsp salt
• 1/2 tsp mustard seeds
• 1/2 tsp urad dal
• 1/2 tsp channa dal
• A bunch of curry leaves
• A bunch of coriander leaves
• A dash of asafoetida
• 2 tblsp oil

• Soak the sago in the buttermilk for 5-6 hrs. 
• Chop the onions and green chillies and curry leaves. 
• Heat the pan and add oil. Add mustard, cumin seeds and channa dal and urad dal. 
• Add onions, chillies and curry leaves to it. Cook for 5 minutes and add this to the soaked sago. Also add chopped coriander leaves to it. Mix it well. The consistency should be like the same for rava idli. 
• Pour these in idli pans and cook them for 15-20 minutes. 
• These idlis are too soft and sticky. They should not be cooked for too long but see to that the sago is cooked well. It comes out by practice.
