Instructions
Brine
Remove the turkey packaging, neck and giblets. Make sure the turkey is completely thawed.
Stir 1 cup salt into the gallon of buttermilk until dissolved, then stir in the 6 tablespoons rub. Separately dissolve the remaining cup salt in the gallon of water. Combine both liquids.
Submerge the turkey in the cold brine and refrigerate at 33–39°F for 10–12 hours. Drain and discard the brine.
Make and Add Butter
If roasting garlic, slice about 1/2 inch off the tops, place each head in an open foil boat and drizzle with olive oil. Smoke at 225–250°F for about 2 hours until soft, or roast at 275–300°F for about 1 hour. Cool and remove the softened cloves.
Beat the softened butter until creamy. Fold in the garlic, 1/2 cup rub and chopped chives. Shape, wrap and refrigerate until firm.
Slice about one-third of the flavored butter into roughly 1/8-inch pieces. Gently loosen the turkey skin and distribute the butter between the skin and meat, working from the sides toward the top.
Sprinkle rub over the outside. Reserve the remaining flavored butter for other meals.
Smoke
Prepare the smoker for about 240°F, using cherry, pecan, apple or another preferred wood. Fill the water pan if your smoker uses one.
Place the turkey directly on the grate, breast side up, and keep it in this position.
Smoke a roughly 12 lb bird for about 6 hours, allowing variation, until the thickest parts of the breast and thigh reach 165°F. Apply smoke for about 3–4 hours.
Rest under tented foil for 20–30 minutes before carving.
Notes
Estimated yield: 12 servings from a roughly 12 lb turkey, consistent with allowing about 1 lb raw turkey per person. The source's ingredient list allows 12–14 lb, but its detailed timing and size recommendation use a 12 lb bird. Brine quantity is about 2 gallons; adjust to fully cover your turkey. The butter recipe intentionally makes extra, with only about one-third used on one bird. Garlic roasting is optional and adds time; use minced garlic for the shorter preparation. Make dressing separately rather than packing the turkey cavity.
