UNTREATED cedar planks, which are sold for this purpose, can be found at most specialty food stores or some grocery or hardware stores. During cooking, check periodically to make sure that the plank is not on fire. Since the plank can ignite when exposed to flames, it is best to keep a spray bottle of water close at hand if needed to extinguish any flames.
Searing Steak on Grill
Searing the steak a few minutes on the grill before placing it on the plank gives it the traditional grill marks, which helps prevent the meat from looking and tasting steamed.
Serve with grilled corn on the cob.
