It's the world's most ancient grilling method, and to my mind, it remains the best. It's practiced on six continents by traditionalists and cutting-edge chefs alike. Propane offers convenience and charcoal burns hot, but the ultimate fuel for grilling is wood. Wood smoke contains more than a thousand flavor-producing compounds: It's the one fuel that delivers both heat and taste. From wood-grilled bruschetta with fire-blistered tomatoes to swordfish with raisin chimichurri and magisterial sear and slide beef tomahawks, today's show brings you the primal campfire pleasure of grilling over a wood fire.
