Creating delicious Homemade Birria Tacos is simple when you follow these steps:

1. Prepare the Chilies: Remove seeds and stems from the guajillo and ancho chilies. Soak them in hot water for 20 minutes until soft.
2. Blend Marinade: In a blender, combine soaked chilies, onion, garlic, apple cider vinegar, cumin, oregano, black pepper, and salt. Blend until smooth.
3. Marinate the Meat: Cut the beef chuck roast into large chunks. Pour the marinade over the meat and mix to coat. Let it marinate for at least 1 hour, preferably overnight in the refrigerator.
4. Cook the Meat: In a large pot, add marinated meat and cover with beef broth. Bring to a boil and then reduce to a simmer. Cook for 3 to 4 hours until the meat is fork-tender.
5. Shred the Meat: Remove the beef from the pot and shred it using two forks. Set aside and reserve the broth for dipping.
6. Prepare Tortillas: Warm the corn tortillas on a griddle until pliable.
7. Assemble Tacos: Fill each tortilla with shredded beef.
8. Garnish: Top with fresh cilantro and diced onion.
9. Serve with Consomé: Ladle some hot beef broth into small bowls for dipping.
