I did one just like a whole turkey. I used the honey brine recipe at the site,brines for a couple of days and smoked at about 250-260 dome temp to an internal temp of 155-160.
I took it off and foiled it for a while to finish it. The only problem I had was I injected some of the brine into the breast and the finished product was a little salty.
I have since done 2 whole turkeys by just brinig for 2 days and they turned out great.
I use a little more honey than called for and don't add it until the brine has cooled to below 160deg. It supposedly breaks down above this temp. I started doing whole turkeys because the price is right this time of year. You can get a whole 12-15 lb one for
about $10 at .69/lb versus the cost of the breast. If you want to,you can buy a whole turkey,cut the breast out for smoking and do the leg quarters some other time. Good luck. /infopop/emoticons/icon_smile.gif
