I recently smoked a boneless / skinless turkey breast with cracked pepper, which is one of my favorite recipes. My injection was a mixture of Kosmos Chicken Soak and LC Fowl Play (using amounts much less than the competition amounts). I had enough left over to use it as a cover brine. Brine time was 24 hours.
After seasoning, I did let them dry overnight. I kept the pit temp around 250° and smoked them for 2 hours. The internal was145° when I pulled them.
The next step was going into a 155° water bath with some butter added to the bag, for 90 minutes.
Really great results... very tender and moist. And the sous vide insured the doneness of the thick and thin areas to be the same.
