I usually don't worry about white smoke when I am cooking burgers or something on the grill. I just throw a ton of chips on the lump charcoal and let it smoke. That doesn't have enough time to make an acrid taste on the meat does it? I like the way my burgers taste usually as long as they aren't overcooked, which I tend to do from time to time sadly.
