The only bad wild turkey I've had was the one I roasted whole. I didn't overcook so the breast was great but the legs, thighs and wings were incredibly tough. A day in the crock pot fixed that.
Since then I've done at least a dozen that all came out great. I cut off the breast meat, cut into 3/4-1" steaks, marinate overnight in 1 cup cider vinegar or wine, 1/2 cup olive oil, 4 cloves of garlic sliced, a thumb-sized piece of ginger sliced, 1 tbsp sea salt, 1 tsp black pepper and 1/4c brown sugar or honey. 2minutes per side on a very hot grill or in a greased smoking hot cast iron frying pan. Tender and delicious.
Leg quarters go in a crock pot barely covered with water or stock on low for 12-24 hours. Drain, pick out bones, cartilage, tendons etc. Shred meat by hand or with a fork, add 16 oz of your favorite barbeque sauce, and back on low for at least 4 hours, no more than 8. Serve on buns like a barbeque beef sandwich, also delicious.
