Preheat oven to 350°F (180°C). Place each fillet on one side of a square of aluminum foil. Butter the opposite side of foil, using 1 tsp. (5 ml) per square. Sprinkle each portion with 1 tbsp. (15 ml) wine, salt and pepper. Then add the dill and lemon slice. Fold over the foil, sealing the edges tightly. Place the salmon packages on a baking sheet and bake in the oven for 15 to 20 minutes.
