Wood is my personal favorite fuel for grilling, in particular, a hardwood like oak, hickory, beech, apple, or other fruitwood. Wood gives you both heat and flavor—a lighter smoke flavor than when you use wood chips or chunks for smoking, but a wood-grilled flavor, all the same. Grill masters from Tuscany to Montevideo back me up on this, and if you’ve ever had a simple sausage, steak, or s’more grilled over a campfire, you know how incredibly flavorful wood-grilled foods can be.
