Grilling over wood
Wood gives you a great flavor when grilling. Just remember: Always grill over hardwood, such as oak, hickory, apple, cherry, and mesquite. Softwoods, like pine and fir, produce too much soot and unpleasant, even dangerous, residues.
There are two basic ways to grill with wood. The first is to use hardwood chunks in place of charcoal. (Look for wood chunks at grill shops or hardware stores.) The second is to toss a log or two on a charcoal fire to achieve that fragrant wood flavor.
