Combine first four ingredients in a zip plastic bag and add salmon. Marinate for twenty to thirty minutes. Place soaked plank on hot grill and close lid. When plank begins to smoke and crackle place salmon with skin side down directly onto plank. Close lid and cook to desired doneness. Salmon is best served medium rare. Do remember fish will continue to cook after being removed from the grill. Serve straight from the plank to create a unique presentation.
