Tur Dhal (1/2 cup) + Idli rice ( 1 cup) + Channa Dhal (1/4 cup) + Green gram dhal (1/2 handful) + Pacharisi (raw rice - 1/4 cup) --> Soak all this in water overnight.
Then grind it with cumin seeds (2 tsp) + dry red chillies (2 or change as req).
Temper some onion + tomato + ulutham parupu (black gram dhal) in oil. Add this to the ground batter. Mix salt and water as req to the batter. Make sure it is not too thin consistency.
