Soak and grind rice and black gram dal a little coarser and thicker than you would grind for idli batter. Add salt and cumin seeds. Mix well.
Spread one big spoonful batter on a piece of plantain leaf or ‘seelanthi’ leaf. Place one spoon scrapped coconut in the center. Fold the leaf. Steam cook this.
This dish goes well with mulagu chamanthi (find recipe on this site).
