Mix together all the ingredients and blend well.

To prepare banana leaves: Wipe leaves with a clean cloth dipped in a weak solution of bleach and water.

Quickly pass the leaves over a medium to low flame. Allow the leaf to get slightly dark, not to burn. Cut the leaves into squares (about 15-20 cm) and set aside.

Grease a square leaf and place 2 tablespoon of the mixture in the center. Flatten a bit. Fold over leaves and tie securely. Boil in hot water for about ½ an hour.

Cool, remove from wrapping and serve.
