I say neither! In a perfect world, we’d all be filling our backyard barbecue with wood and nothing else. Yes, it’s a little more difficult to find. Yes, it burns hotter and faster. But it brings the flavor.
Between charcoal and gas, I choose gas. Both are strictly for convenience and gas is a heckuva lot easier than charcoal. And there’s less cleanup.
My propane barbecue has a grate between the flame and grills, where I place soaked wood chunks and/or chips. This way I get at least a little of that good smoky flavor.
Ah, but what kind of wood? It’s a matter of prefence. I don’t much like mesquite, it’s just an overgrown weed after all, and hickory is fair. For me, it’s pecan wood every time.
