This thanksgiving was my first whole smoked turkey. I always like to cook the biggest turkey I can find they usually weigh in about 24 lbs ( I have 3 teenage boys to cook for) and it came out great! I used Alton Browns turkey brine its veggie stock, candied ginger, whole peppercorns, allspice berries, kosher salt and brown sugar can't think of exact measurement right off hand but you can look it up on food network. I recommend it to anyone and smoking the turkey made it that much better!! I used my chargriller that I recently reconfigured and it worked really well and that big ass turkey fit perfect. I think the breasts were about 4 lbs!
