I have smoked many pork butts and I have always been a foiler and I have liked my results but lately I am getting so sick of the soft mushy bark I have been getting. Normally I will foil it around 165-175 and the end result will be soft bark but yesterday I did two and they were really soft. So soft that all of the bark went into the garbage because it was nothing but soft snot. Maybe I just over did it with the liquid in the foil I'm not sure? Like I said I will normally foil them up around 170ish so that some good bark has formed but yesterday I had things going on so I foiled them at 160-165 and the end result unacceptable in my book. I suppose foiling them at 165 when there wasn't a huge amount of bark formed yet could have also contributed to the soft outer layer. The next butt I do I am not going to foil it and see what happens. I have never been a big fan of super think bark so I think that is why I have always foiled them so this should be an interesting experiment running them unfoiled the whole time. I however will foil them once they are done and let them rest in the cooler with towels. I know lots of you guys/gals don't foil at all so I think it's time for me to give it a shot. I had an upset stomach and I was pissed of about the outcome of the bark so I didn't even try any of the pulled pork but the wife did and she said it was awesome so it must still taste good as usual so that makes me feel a bit better.
