This is my second attempt at pulled pork. First, I started with a cheap 4lb shoulder. It was wrapped in some stretchy netting, when I removed it the piece of meat fell into two almost equal chunks. Great, I thought, it will take half as long to cook! I rubbed it down using a rub that I really like. Started with only charcoal and got to smoking! After about 1.5 hours, I started adding pre-burnt oak and hickory coals. I did a bang up job, I thought. Kept the temps right between 200-230 for about 5 hours, the internal temp was at 175 when I took it off. But the thing wouldn't pull apart! It was the tastiest pork I have ever had in my life, however. I have never in my life woke up in the middle of the night with a pork craving. So I'm wondering what I might have done wrong, or maybe I just don't know how to pull pork apart?
