In a bowl, mix cassava, coconut sugar and aniseed.
Divide mix in 4 parts and wrap each in banana leaves in a rectangular pillow-like parcels, wrapping the leaf over itself in 2-3 layers without breaking it if possible.
Tie the parcels with kitchen twine.
Fill a pot with enough water to cover the parcels and bring to a boil.
Pop the parcels in the pot and boil for 30 minutes.
Fish the parcels out of the water and let cool down enough to unwrap and enjoy.
Chapana is usually eaten warm, although some people enjoy it cold or at room temperature.
