Tuna is an ideal dish to cook over the hot coals in your arctic cabin, it's meaty texture means that it will hold well together during the cooking. Serves 2
Put the first six ingredients into a shallow dish and mix well together.
Add the tuna and spoon the sauce evenly over.
Cover and leave to marinade for about an hour turning the tuna over once. Transfer the sauce coated tuna steaks to the barbecue and cook over the hot coals for 4 to 5 minutes on each side, or until very nearly cooked through.
Tuna becomes rather dry if overcooked. Stop cooking when it is still slightly translucent at the centre
