First off I gotta admit I'm no turkey fan. I was too tired to brine it Sat night, so Sun afternoon I injected the 12-pound bird thoroughly and let it rest in the fridge for an hour or so. Then I smoked it breast-side up until the breast was 168, and let it rest for 30 - 45 min.
Color was a beautiful brown with the exception of the ugly gray spot. I used 3 oz of cherry at 250 deg. Injected with cajun butter sauce and rubbed with cajun spice. Didn't rub between breast and skin.
Results: very moist, but bland. Skin was rubber. Needed more smoke (I like smoke flavor).
Next time I think I'll just fry it--the only way I've found that I like turkey.
Mistakes: 1) didn't brine, 2) didn't rub butter/rub between skin & meat, 3) didn't use enough wood, 4) I wasn't home to crack the door evey hour like I normally try to do when cooking a smoker full of meat (to release excess moisture and prevent the ugly gray spot, and 5) didn't just fry it.
