didnt take a pic, was serving pulled pork to new neighbors LOL. anyways this has never happened to me, a lightly tanned pork butt cooked low and slow for 17 hours. no bark at all. to complicate things i did two things differently that ive never done before with the last hundred or so butts, no mustard and lit the egg thru the lower vent instead of on top. other than that it was a typical cook for me, rub, additional brown sugar, some cayenne,apple wood for smoke, add an injection of apple juice and vinegar with some heat half way thru the cook, an indirect setup etc. neighbors didnt know the difference but .....
so what was it, lighting method or no mustard.
