Preparing the Pork: Place the pork shoulder chunks in the slow cooker.
Adding Liquid: Pour the pork broth or water over the pork. If using water, the pork will create its own flavorful broth as it cooks.
Seasoning: Sprinkle the salt over the pork, adding black pepper if using. Adjust the seasoning to your preference.
Slow Cooking: Cover and cook on low for 8 hours, or until the pork is very tender and falls apart easily.
Shredding the Pork: Once the pork is cooked through, use two forks to shred the meat directly in the slow cooker. Stir the shredded pork back into the soup, ensuring it's well mixed with the broth.
Final Adjustments: Taste the soup and adjust the seasoning if necessary. The soup should have a rich, concentrated pork flavor.
Serving: Serve the soup hot, ensuring each bowl has a generous portion of tender, shredded pork.
