• Rinse and clean your pork shoulder. Pat it dry with paper towel and place it in a glass dish.
• Using an immersion blender or bullet, mix the remaining ingredients together EXCEPT for the butter or ghee, you'll be using that later.
• Rub the mixture all over the pork. Cover tightly and refridgerate for 12-24 hours.

Roast Day

• Remove the pork from the fridge. Let it sit at room temp while you prepare the cast iron.
• Preheat oven to 250°F
• Add a good amount of butter, or ghee to your cast iron. When the cast iron is hot, sear the pork on every side (the top, bottom and sides). Some fat should release, adding grease to your pan, which will make searing easier. If you have a cut with not a lot of fat and your pan is drying, add a bit of olive oil to the pan.
• When pork has been seared on all sides, place the cast iron in the oven, uncovered. Cook for 2 hours, then flip the pork over. Cook for another 2-3 hours.

  If you're leaving and don't have time to flip the pork, that's okay. Just heat the pork under the broiler for a few when it's done cooking, so the top gets crispy. Careful though, the broiler can burn things very quickly.
• After the 4-5 hours, you should be able to 'pull' the pork apart with a fork. Serve on its own or with a side of add BBQ sauce.
• When storing leftovers, be sure to include some, if not all, of the rendered pork fat in the pan. This will keep the meat from getting dry!
