A couple of tips... First, I use Italian dressing doctored with Worchestershire sauce, salt, pepper, and garlic for both marinade and injection. I strain the mixture, inject and let sit at least overnight as James stated. Second, I use the "Sittn' Turkey" stand filled with beer/marinade mixture.
This thing is made of glazed ceramic, which cleans itself in the dishwasher. I'll be frying a turkey, and maybe smoking 2 or 3 in the new smoker. Please post pics of your birds, and thanks James for the post.
