Plucking a wild turkey is, frankly, a pain in the rear, and there's so little fat on the bird it's not really worth the time or effort. A skinned breast, however, does have a tendency to dry out, creating a tough exterior. One way to combat this is by using what's called a mop. I use equal parts apple cider vinegar and water. Other folks use straight apple cider. There are a number of mop recipes out there, so find one you like. And contrary to the name, you don't have to mop it on. I use a spray bottle and coat the meat two or three times over the course of the cooking time.
