Instructions: Blend all the marinade ingredients until smooth and reset the fish steaks in the mix for about 1 hour.

Meanwhile soak the wood chips in warm water and drain.

Preheat the grill to maximum (if gas) or until the charcoals are white in colour and very hot. Scatter a handful of damp chips over the coals until the chips are smoking then cover with the kettle lid and then grill the tuna about 6 inches above the coals, for about 4 minutes each side, basting with the marinade once when turning the steaks over and seasoning.

When ready, the fish should be brown outside and have a pink centre.
