It doesn't take long to prep your meat for this cook, so before you do anything, I'd get your smoker up to temp. We want to start out at 225 degrees.
Place your pork shoulder on a cutting board, fat cap up.
With a sharp knife, score the fat cap in a one-inch checkerboard pattern. This will allow the rub to penetrate down into the meat on all sides.
Cover the entire cut of meat with your garlic-infused olive oil, and then generously apply your rub on all sides. Be sure to really massage the rub into any folds in the meat, you want as much delicious bark as possible!
Place the pork shoulder on the smoker, which should be at 225 degrees.
In a small spray bottle combine the Apple Cider Vinegar and Olive Oil
After 2 hours, increase the temp on your smoker to 250, and generously spray your pork shoulder. Continue spraying at the top of each hour, but otherwise, leave the door on your smoker closed!
Every cut of meat is different, but it typically takes about 90 minutes per pound to get your meat up to the magic temp of 200-203 degrees. Once you're there, pull the pork shoulder from the smoker, double wrap it in foil, and place it in a cooler with some towels.
Let the shoulder rest in your cooler for 90-120 minutes. This will allow the juices in the meat to redisburse, giving you some AWESOME flavor.
When it's time to pull the pork you can use your hands, forks, or claws. I like the claws I use... They keep my hands clean and safe from being burned (the meat will still be very hot)
Be sure to remove the shoulder blade, and discard any large chunks of fat or bone you come across while you are shredding.
Serve!
