- Season the pork shoulder with salt, pepper, cumin, and cinnamon, massaging the spices into the meat for even coverage. 
- In a large skillet, sear the pork shoulder on high heat until each side develops a deep golden brown and releases a rich aroma, about 3-4 minutes per side. 
- Transfer the seared pork to your slow cooker, add the roasted garlic cloves and pour in the chicken broth to provide moisture and flavor. 
- Cover the slow cooker and cook on low for 6-8 hours, until the pork is fall-apart tender and shreds easily with a fork. 
- While the pork cooks, prepare the slaw: core and thinly slice the apples and fennel bulb, then combine them in a mixing bowl. 
- Whisk together the apple cider vinegar and honey, then toss the mixture with the sliced apples and fennel to coat evenly. Let sit for a few minutes to allow flavors to meld. 
- Once the pork is cooked and tender, remove it from the slow cooker and shred it using two forks, discarding any excess fat or gristle. 
- Warm the tortillas in a dry skillet or microwave until soft and pliable, about 20 seconds. 
- Assemble the tacos by spooning generous amounts of shredded pork onto each tortilla, then top with a handful of the apple fennel slaw for crunch and freshness. 
- Serve the tacos immediately, with optional extra dressing or fresh herbs if desired.
