Did a 7.5lb frozen pork butt for the 4th. Thawed it, rubbed it with mustard and killer hogs hot bbq rub. Stuck a few garlic cloves in her for good luck. Started the cook at 830a on my PB850 using comp blend pellets, at 225 deg. My PB temp probe measured at 1130p (15hrs) was 164. Not wanting to leave the smoker unattended overnight, I moved the butt to my crock pot for the remaining overnight slow /low cook. At 600a it was a perfect 198-205 using my therm instant read, it was just as tender (like hot knife in butter) as Malcolm Reed describes it. After pulling it and separating out the fat, put it in the fridge until the party that night. Warmed it back up in the crock pot, and the party people devoured it as pulled pork sliders (king rolls).
