Who says you can get a wood grlll flavor on a gas grill? I lay wine barrel staves (could also be olive wood chunks or any hardwood chunk) between the Flavorizer bars under the grate. When the start to catch fire, I put on the steak. I'm partial to Best of Barbecue Wine Barrel Staves--surprise!, but any hardwood stick or chunk will work. Note: this is dry wood, not soaked. In this instance you want a light wood grilled flavor, not the heavy smoke of true barbecue. What's YOUR favorite way to grill over wood?
