Prepare banana leaf cones life shown in the above picture.
Prepare a steamer.
Grind the par-boiled rice, jackfruit, coconut and jaggery to a very thick, slightly coarse batter. If required add very little water to assist grinding.
Fill 3 tablespoons of mixture in the cone and seal it with a tooth pick. Repeat until you have finished the batter.
Place the cones in a steamer and steam for 10-12 minutes.
Once done remove from steamer, unwrap in individual serving tray and serve hot or cold.
These cakes can be served with ghee or coconut chutney with a cup of filter coffee.
