Hello, so I've been smoking since late summer last year. Seems all my smokes take much longer than the recipe calls for. My smoker, small Pit Boss, does fluctuate temp, but I think that's normal. I have used a probe to check the temp of the smoker and it's consistant to what the smoker temp reading is. For instance, I smoked a 3 pound turkey roast yesterday. Outside temp was high 50's. Smoked it at 250, took SIX hours. I've also done butterflied pork butt, meatloaf, whole chicken, and salmon. All take longer than expected. Here is the turkey I did yesterday. All my food is turning out good - great, just takes long time.
