Measure the butter, honey, lemon, soy sauce, pepper, and garlic into a bowl. Mix the ingredients with a spoon. Brush both sides of the halibut fillets with the marinade. Grill the halibut for 5 minutes on each side.
Measure 2 tablespoons (28.5 grams) of melted butter, 2 tablespoons (42.5 grams) of honey, 2 teaspoons (11 grams) of soy sauce, and 1/2 teaspoon (1.1 grams) of pepper into a small bowl. Add the juice from a medium-sized lemon and 2 cloves of minced garlic. If you don't like garlic, simply leave it out. Use manuka honey for maximum health benefits. Continue to mix the ingredients until they are thoroughly combined and the marinade has an even texture. This helps the marinade to have a consistent taste when it is cooked. If there are any lumps in the mixture, use the back of the spoon to squash them. Dip a pastry brush into the marinade and paint it over the halibut fillets. Make sure that the entire surface of the fish is covered with the marinade. This helps to make the skin crispy and full of flavour. If you don't have a pastry brush, use a spoon to drizzle the mixture over both sides of the fish instead. Place the halibut onto the grill for 5 minutes. Use a metal spatula to turn the fish over and cook it for another 5 minutes. Insert an instant-read food thermometer into the middle of the fish and check that it has reached 135F (57C). This indicates that the halibut is ready to eat. Enjoy!
