PREP: Preheat oven to 325 degrees Fahrenheit and place rack in the lower third of the oven.
SEASON AND SEAR PORK: Add oil to an 8-quart Dutch oven and heat over medium-high heat. Mix salt, pepper, cayenne, and Bohemian Forest seasoning in a small dish. Rub spice mixture all over the pork. Brown pork on every side. You may have to hold the meat up with a large meat fork to brown the shorter sides. It should be well-seared and dark brown when you’re done.
ADD VEGETABLES AND LIQUIDS: Add onion, carrots, celery, and garlic in the pan around the meat. Pour in beer and add enough broth so the liquid comes halfway up the meat. Add bay leaves. Cover and bring to a simmer.
BRAISE FOR 6 HOURS IN THE OVEN: Put the covered Dutch oven into the oven and cook for approximately six hours or until meat is fork tender or falling off the bone. Turn pot around every hour or so and check every two hours to make sure the liquid still comes halfway up the meat. Add more broth as needed.
USE MEAT NOW OR COOL OVERNIGHT TO USE LATER: To use meat today, remove pork from braising liquid, and rest on cutting board until cool enough to handle. Strain braising liquid, saving solids or discarding as needed. Shred (pull) meat using two forks or your fingers and, adding strained braising liquid and/or BBQ sauce, use for sandwiches, BBQ, etc. (See other ideas below.) Discard bone, fat, and gristle. To use meat later, let meat and liquid cool in the Dutch oven for an hour or so and then cool completely covered overnight in the refrigerator. You can then remove the fat on top of the liquid and shred before using meat in recipe(s) of your choice. Option: Heat unstrained broth and vegetables (after removing the pork from the pot) and purée into a gravy using an immersion blender or processed in batches in the food processor. STORAGE: Store tightly wrapped in the refrigerator 3-4 days and in the freezer in covered airtight containers or heavy duty freezer bags for up to 3 months.
