Thanks, Jim.
Brining is really the rage in food circles these days, thanks, in part, to Alton Brown's Food TV show on brining turkey.
The reason I'm scratching my head is that, having roasted turkeys outdoors every Thanksgiving and Christmas for 30+ years, I can count the "dry" birds on one hand -- and they were all a result of waiting for that silly plastic popper to go off and overcooking the bird. To me, the biggest advantage of roasting the bird outdoors is that it seals the skin and produces meat with a moisture level and texture that makes all indoor cooked turkeys seem like rubber.
Intuitively, a saline brine approach seems like something that you would use for smoked turkey lunch meat rather than a true roast turkey. Or, to look at it a different way, the difference between a smoked ham and a pork roast.
Maybe the difference is that I cook turkey at high temperatures and it cooks in roughly the same time frame on the outdoor cooker as it would in the oven - 3.5 to 5 hours depending on the usual factors. I also cook fresh turkeys, rather than frozen, which I'm sure helps.
I agree about chicken breasts. I've cooked my share of lousy ones. I've finally settled on a way that produces consistently good results: again, high-heat indirect roasting with NO sauce until it's served (or at the most for the last ten minutes of cooking) and definitely NO direct grilling heat. You have to be really careful to not overcook them.
I guess I'll have to try brining some chicken breasts and see what I think.
