- Place the fish pieces into a blender or food processor and pulse for a few seconds, then add all the other ingredients, except the banana leaves and grind to a thick paste. Set aside.
- To make the banana leaves flexible so you can fold easily, scald the banana leaves by pouring boiling water over them in a basin. Drain and place the leaves on a clean work surface. Scoop 3 heaped tablespoons of the fish mixture onto the centre each piece of banana leaf (or aluminium foil). With a firm hold, fold one side of the banana leaf over the other to form an elongated package. Then hold the ends of the banana leaves and fold in both corners to form a triangular tip. Seal package on both ends with toothpicks. Repeat until all the fish mixture is used up.
- Grill each parcel directly over the hot charcoal or in a preheated oven for 10 to 15 minutes, turning from time to time until the banana leaf wrapper is charred. Serve them hot.
