How to Make It
Soak a 16-by-8-inch cedar plank in water for 1 hour. In a large, shallow baking dish, combine the wine with the apple juice, salt, bay leaves, peppercorns and juniper berries. Add the salmon, turn to coat and refrigerate for 30 minutes.
Light a grill. When the coals of a charcoal grill are covered with a light gray ash, push them to the sides and set a disposable drip pan in the center. If using a gas grill, turn off the center burner. Remove the salmon from the marinade, brush off the seasonings and lay the fish skin side down on the soaked cedar plank. Brush the salmon with olive oil and set the plank in the center of the cooking grate for indirect grilling. Cover and grill the salmon until just cooked, about 30 minutes; brush the salmon with the sauce during the last 10 minutes of grilling. Serve the salmon directly from the plank.
