Step 1

Put the lime juice in a wide bowl with the salt and garlic. Add 100ml/3½fl oz water and the fish fillets, ensuring the fillets are covered. Leave the fish to soak for 1–2 hours then remove and pat dry with kitchen paper.

Step 2

Mix all of the rub ingredients together in a small bowl. Spread the mixture on a plate and dip the fillets of fish in it, coating both sides.

Step 3

Preheat your barbecue and cook the fish for 3 minutes on each side. Alternatively, heat a little oil in a frying pan and fry the fillets over a high heat for 3 minutes on each side.
