Grilling Norwegian salmon on a plank makes it tender, and a tasteful marinade gives it an extra flavour. A plank of cedar or aspen is preferred for this recipe.
Soak the wooden grilling plank in water for 2-3 hours before grilling.
Rinse the salmon in cold water, dry with a paper towel and place in an airtight container.
Finely chop garlic and ginger, and mix with rice vinegar, soy sauce, honey, pepper and lime juice for the marinade.
Pour marinade over the salmon and close the lid. Marinate for 15 minutes, turn the fish and let marinate for another 15 minutes.
Remove the salmon from the marinade and place in the middle of the grilling plank.
Grill the fish for approx. 15 minutes. Cover with a lid if you have available.
Sprinkle spring onion and sesame oil over the fish at the end of the cooking time.
Crush mint and sugar together in a mortar and mix with yogurt.
Season with lime juice and salt to taste.
Cut the sweet potato into wedges and place in a sheet of greased aluminium foil.
Sprinkle with salt and pepper and grill until tender.
Serve the salmon with mint yogurt and sweet potato wedges.
