My name is Pappyvic and I'm new to smoking. smoked babybacks forst time came out ok. the 2nd try was a 5lb pork loin roast cooked 7.5 hrs at 225 was still pink. today i tried to smoke a 5lb chicken brined overnight cooked for 5 hrs at 225 internal temp said 165, but was still pink. i'm using a master forge gas smoker. a redi-check et-73 thermomoter i use hickory chunks what am i doing wrong?
