Just like a technique used for centuries by Native Americans, use our Set of 6 Grilling Planks when grilling to add exceptional flavor and tenderness to meat, fish and vegetables. Simply soak plank in water to prevent scorching, place on grill and cook as usual. The result is a subtle, smoky flavor and delicious, butter knife tenderness. Set includes two of each: cedar, alder, and maple. Recommended for outdoor use only.
