Toast dried chiles in a dry pan over medium heat until fragrant, then soak in hot water for 15 minutes.
Blend the softened chiles with onion, garlic, cinnamon, oregano, cloves, cumin, vinegar, and 1 cup of beef broth until a smooth paste forms.
Season beef with salt and pepper, then sear in a large heavy-bottomed pot until browned on all sides.
Pour the chile marinade and the remaining beef broth over the meat, adding the bay leaves.
Cover and simmer on low heat for 3.5 to 4 hours until the meat is completely tender and shreds easily.
Remove meat from the pot, shred using forks, and strain the liquid to serve as consomé.
