Here's how I'm doing mine:
I'll brine the bird for at least 24 hours, then air dry for 8 hours in the fridge. I'll take it out about an hour before it goes on the smoker and put some ice packs on the breast while the thighs warm up. Right before it goes on, I'll inject with one stick of lightly salted butter melted, with a half teaspoon of white pepper mixed in. I'll give it a nice vegetable oil massage and sprinkle with fresh ground black pepper, kosher salt, granulated garlic, sage, thyme, rosemary and a little paprika for color. I'll stick some onions, garlic cloves, carrots and celery in the cavity and cook at 325 until the breast is 165*. Rest it for 45 minutes loosely tented then carve. Merry Christmas!
