Score the fat on the pork butt, then slather it in yellow mustard for the binder.
Season the pork evenly on all sides with the BBQ rub.
Place the pork butt directly on the grates of the smoker with the fat cap down.
After 90 minutes, begin basting the pork butt with the mop sauce every 60-90 minutes.
Smoke for 8-10 hours until the internal temperature reaches 203°F.
Remove from the smoker and let rest for 30-60 minutes, then shred and serve.
Notes
What pellets to use – Any pellets will work because pork is pretty friendly with most woods. I like to use a blend of Oak and Pecan pellets when I’m smoking pork.
