maravalli kilangu Adai - Tapioca Adai recipe - Breakfast or dinner recipes

I love Maravalli kilangu / Tapioca. Last trip to India I tasted this at my friends house.. It tasted like adai with very little variation. She was expecting me to find the difference as I am food blogger, I initially thought it is with millet. but later she told me she has used Maravalli kilangu. I am surprised. I noted down the recipe from her and wanted to try it out. We do get this kilangu / yam. Loved the texture and taste of it. 

Idli rice - 2 cup
Toor dhal - 1/4 cup
Red chillies - 4-5 (adjust to your spice level)
maravalli kilangu - Tapioca - 2 cups (grated)
Salt to taste
Asafoetida- 1/2 teaspoon
Shallots / small onion - 1 cup (chopped finely)
Coriander leaves - 1 tablespoon
Curry leaves - 1 tablespoon

Soak rice, dhal and red chillies for 4-5 hrs. Grind grated tapioca and chillies separately
