So this past weekend I was tapped to do a pp smoke for a graduation party. So my better half grabbed me 20 lbs of butt. It was a smoke from hell, but here are my questions to figure out what besides what I already knew went wrong. 1) I normally do shoulders, do butts require a different prep? 2) I cooked it with the fat cap up. Would I have been better off with it down? 3) if it passes the probe test before 200 would that cause a more shredded product than pulled ie. Stringy vs fall apart smaller pieces? I have done a fair share of pp and have almost always had awesome results. However, this time I was displeased with my finished product. People still loved it, but when you know it's not your best it's a jab to your confidence and pride. Some issues I had were that temp regulation on my masterbuilt 40" gasser was almost impossible due to higher winds. Struggled to reach 140 in 4 hrs. Then it cooked at a higher temp and hit 190 really quick so I backed off heat and it dropped and stalled at 180 for a long time then pulled through and passed probe test. I know those hurt the smoke pretty bad, but I am wondering if I needed to do something else based on my questions.
