Prepare the Pork: Trim any excess fat from the pork shoulder and place it in the slow cooker.
Add Aromatics: Scatter the sliced onion and minced garlic around the pork.
Season: In a small bowl, mix the apple cider vinegar, olive oil, ground ginger, turmeric, cinnamon, salt, and pepper. Pour this mixture over the pork and onions in the slow cooker.
Cook: Add water around the pork. Set the slow cooker on low and cook for 6-8 hours or until the pork is very tender and easily shredded.
Shred: Remove the pork from the slow cooker and shred it using two forks. Return the shredded pork to the slow cooker and mix it with the juices.
Serve: Serve the pulled pork on a plate or in AIP-friendly wraps or over roasted vegetables.
