Hi Bill,
To foil or not to foil... I've done it both ways with most cuts where foil is commonly used. I prefer foiling. But, foiling is not a requirement and good barbecue can be done without foil. I'm guessing that, if all barbecuers had an in-depth knowledge of the chemical process of collagen breakdown and of the latent heats of water, most would choose foiling.
What I find interesting is the often repeated argument that foiling is somehow cheating and is not true to original barbecue. That's one of those areas where, if a person wanted to stay true to original barbecue, they would likely find themselves in search of a cooked dead animal found in the aftermath of a forest or brush fire started by lightning. That's a likely scenario for the true, original barbecue.
Anything else that has developed since is not true to the original tenets of barbecue. That would mean: No modern meat market or grocery store. No porcelainized steel smokers. No manufactured charcoal--lump or briquette. No thermometers. No matches or piezo starters. On and on and on.
I think it's a shame for folks to close themselves off from any advancement in technology and/or process that may make their barbecue better. And, of course, what constitutes better is as variable as the preferences of those eating the barbecue.
