This recipe comes from "Taste of Home" and combines two of the Pacific Northwest's most ubiquitous ingredients, salmon and berries. The cedar planks can only be used for outdoor grilling and lend a delightful smokiness. The recipe would still be good minus the cedar planks and cooked on a grill pan indoors.
Soak the planks in water for at least one hour before using.
Use a food processor to combine blackberries, wine, brown sugar, and hot sauce. Season with 1/8 teaspoon each of salt and pepper. Strain the sauce and discard any seeds. Stir the shallots and garlic into the sauce and set aside.
Preheat an outdoor grill for medium high heat. Place the planks on the grates, close grill, and heat until the planks start to crackle and emit smoke, about 3 minutes. Turn planks over.
Season salmon with the remaining salt and pepper. Place on the planks. Cover the grill and cook until the salmon flakes easily with a fork, about 12 to 15 minutes. Serve with sauce.
