I don't make turkey BBQ, but I generally shred/pull turkey & serve it in broth/au jus. The important part of that is to just cook the daylights out of it. LOL I start my bird on 425 for 20 - 25 minutes & then lower the temp to 300. Cook it until the leg is all but falling off the carcass - not just until the "popper" pops or to the required internal temp. I also always cook mine covered the entire time. My roaster has a lid - foil just doesn't do the same thing.
I use a variety of spices for the rub & also put oranges or lemons under the skin & inside the carcass. But if you're looking for BBQ, this might do. Of course a turkey won't fit in a slow cooker, but the method above should work. I copied it down from someone here a while ago - so the comments are theirs, not mine.
Tender Barbecued Chicken
Reminiscent of WL-Whispering Canyon
1 broiler/fryer chicken(3 to 4 pounds, cut-up)
1 medium onion, thinly sliced
1 medium lemon, thinly sliced
1 bottle (18 ounces) barbecue sauce
3/4 cup regular cola
Place chicken in a slow cooker. Top with onion and lemon slices. Combine barbecue sauce and cola; pour over all. Cover and cook on low for 8-10 hours or until chicken juices run clear. Yield: 4-6 servings
That's the real recipe. Here's what I did.
3 boneless, skinless chicken breasts
1 medium onion, chopped
1/2 cup barbecue sauce(K.C. Masterpiece)
1/2 cup Pepsi
Cooked 6 hours on low.
This chicken was moist and delicious. Most importantly, we were reminded of our happy memories of the Wilderness lodge.
