I started some pork butt this morning at 8:00. I injected with apple juice, water, salt, sugar, worchestershire. Meat was on the smoker until 2:30 when an emergency took me away until 6:00. At that time the butt was 156 degrees in the center. I had to think quick so I turned my propane smoker all the way to low and had to hit the road. When i came home the smoker temperature was only 150 and the butt was down to 120. I am in Iowa and the temperature outside is 15 degrees so it is cold outside which impacted the temp of the smoker. My question is, are the butts still good or should I pitch them?
