Step 1

For the marinade, mix all of the ingredients together and place in a non-metallic bowl. Add the fish and leave to marinate for at least 2 hours, or preferably overnight.

Step 2

Preheat the oven to 200C/180C Fan/Gas Lightly oil a non-stick baking tray.

Step 3

Place the fish, skin-side down, on the baking tray and spoon over 2 tablespoons of the marinade. Bake for 10–12 minutes, until just cooked.

Step 4

Preheat the grill to hot. Spoon the remaining marinade over the fish, place the baking tray under the grill and grill until golden brown. Alternatively, use a chef's blowtorch.

Step 5

Serve with the lime halves to squeeze over the fish.
