For centuries, Native Americans used cedar planks to grill fresh fish and game, imparting a smoky flavor to foods. Now, you can replicate those rich flavors with this set of cedar grilling planks. Just one plank is large enough for two servings of food. Add an extra plank or two if you're cooking for larger groups. It works on both gas or charcoal barbecues. Just soak the planks in water first to help prevent them from splitting as they heat up. The bottom and sides of the plank will become blackened as your food grills; just toss the plank after grilling and use another one the next time. Not intended for indoor use.
