To Prep
Cut banana leaves into 12-15 pieces, approximately 20cm long and rectangles-shaped. Soak in hot water until softened. Drain and pat dry.
Blend the spice paste ingredients in a food processor until smooth.
Chop the fish fillet into small pieces, then blend with the rice flour, kaffir lime leaves, salt and sugar until a smooth paste forms.
Transfer the fish paste to a mixing bowl. Add the spice paste, eggs, and coconut milk, then mix until well-combined.
Place about 1 tbsp of the mixture in the centre of a banana leaf piece. Fold the leaf over the filling, tuck both ends underneath to form a parcel, and secure with toothpicks. Repeat with the remaining mixture.
To Cook
Bring water to a boil in a wok or steamer.
Arrange the parcels in the steamer basket and steam over rapidly boiling water for 10 minutes.
Carefully unwrap the banana leaves and serve the otak-otak hot.
