I just smoked an 11 pounder for a trial run this past Sunday. Heat deflector in place, roasting pan sitting on deflector, turkey spatchcocked and placed on main grate.
Larry, I did your half and half wine and water in the roasting pan and lightly dusted the turkey skin with baking powder salt, and pepper.
I cooked at 325 with Apple wood and finished in a little over an hour. The bird was nice and crispy. I was amazed at how fast it cooked.
I was worried about the drippings burning. All of the liquid evaporated, but the drippings did not burn. This will definitely e my standard moving forward.
