Start by removing the stems and seeds from the dried chiles. Lightly toast them in a dry skillet for about 30 seconds per side — this enhances their smoky flavor. Then boil them briefly until softened and blend with roasted tomatoes, onion, garlic, and all the spices until smooth and velvety.
Season your beef generously with salt and sear in a little oil until browned on all sides. Pour in your chile sauce and beef broth, toss in bay leaves, and let everything simmer on low heat for about 3 hours until the meat is fall-apart tender.
Once the beef is tender, shred it using two forks. Strain and reserve some of the braising liquid — this becomes your dipping consomé. Dip tortillas into the top layer of the broth (the oily red part), fill with shredded meat and cheese, and cook on a skillet until the cheese melts and the tortillas are crispy.
