Did three 12 pound turkeys in my Lang 60. Started this morning, the turkeys went into the prewarmed smoker at 1:30. I used the Slaughterhouse recipies posted here. I added in rubbing down the turkey skin with mayonaise so it would come out crispy (read about this in one of the posts) before I put the rub I was using on. One bird was for my neigbor (first thing for someone else, hopefully not the last) and he needed it by 11:00. I ran the smoker from 250 to 350 on the smoker guage, it was less than that (starting about 50 degrees less) on a maverick ET-73 probe next to a bird. I used hickory to smoke it. The birds came out coal black in color, not golden brown. Any ideas what would cause this? We just pulled the skin off and the meat still tasted good.
