These nicely sized planks [5 inches x 16 inches] are used in fine restaurants and gourmet meal preparation. Cooking and grilling or seafood on 100% natural cedar wood planks increases the food's juice retention while instilling a delightful wood smoked flavor. Each plank can hold several steaks, burgers or fish. To use the planks, merely soak in water up to two hours before using to prevent them from splitting or scorching once on the hot grill. The advantages Northern [Eastern] White Cedar has over Western Red Cedar is that it better enhances the flavor of the food, can be re-used, and doesn't split as readily. Try them once and you may never again grill without them!
