To make the pork: Preheat a smoker to 250° F.

Season the Boston butt generously with salt and pepper and smoke it for about 6 hours or until fork tender.

To make the sauce: In a small saucepan, mix together the vinegar, orange juice, sugar, salt, garlic powder, orange zest, pepper flakes, and black pepper. Bring to a simmer and stir a few times. Remove from the heat and let the sauce cool completely.

Shred the pork with 2 forks or your fingers and mix it with a third or so of the sauce. You might want to use more sauce. It’s up to you. Spoon the sauce and meat on the buns and serve the remaining sauce on the side.

Note: To cook the pork in a slow cooker: Put 2 sliced yellow onions in the bottom of a slow cooker. Season the pork butt with salt and pepper and then put on top of the onions. Add 2 cups of orange juice and 2 teaspoons of liquid smoke. Cook on low for 6 hours or until pork is fork tender. Serve with the sauce as described above.
