#### **Step 1: Prep the Beef**
Trim excess fat from the beef and cut it into large chunks for even cooking.
#### **Step 2: Make the Marinade**
In a small bowl, mix chopped chipotle peppers, adobo sauce, lime juice, apple cider vinegar, minced garlic, cumin, oregano, smoked paprika, salt, black pepper, and ground cloves.
#### **Step 3: Slow Cook the Barbacoa**
Place the beef chunks in the slow cooker and pour the marinade over them.
Add the beef broth and bay leaf, stirring gently to coat the beef.
Cover and cook on **low for 8 hours** or **high for 4-5 hours**, until the beef is fall-apart tender.
#### **Step 4: Shred & Serve**
Remove the bay leaf and use two forks to shred the beef directly in the slow cooker.
Stir the shredded beef into the juices, letting it soak up the flavors.
Serve in warm tortillas with your favorite toppings.
