500g Beef chuck
200g Diced braising beef
6 ancho chiles (ends trimmed and de-seeded)
6 guajillo chiles (ends trimmed and de-seeded)
3 chiles de arbol (ends trimmed and de-seeded)
1 white onion (peeled and halved)
7 garlic cloves (peeled)
5 large tomatoes
1 tablespoon black peppercorns
1 teaspoon dried oregano
1 teaspoon cumin seeds
1 teaspoon coriander seeds
1/2 teaspoon ground cloves (grind down whole cloves)
1/2 cinnamon stick
3 bay leaves
1 teaspoon vinegar
3 cups beef broth
1/2 cup chopped coriander
1/2 white onion chopped
Oaxacan cheese or mozzarella
Bring the meat to room temperature, about 30 minutes and then sprinkle on all sides with salt and pepper. In a large skillet (or pan), set over medium-high heat, add the olive oil. When hot, add the meat and sear on all sides until browned. You’ll have to do this in batches. Transfer to a bowl.
Meanwhile, in another medium pot, add the dried chiles, halved white onion, garlic cloves, tomatoes, spices, bay leaves and add cold water until it covers everything. Place over medium heat and simmer gently for about 10 minutes. Pour through a strainer and transfer everything, including the whole spices to a blender. Add the vinegar and about 1 cup of beef broth and blend until very smooth, about 2 minutes. Add salt to taste.
Preheat the oven to 140 degrees Celsius. Add the meat back to a large casserole dish or oven proof pot and pour the sauce over it. To the blender, add the remaining 2 cups of broth or water and swirl it around to pick up any leftover sauce and pour it into the oven pot. Place over medium heat until it reaches a gentle simmer and then immediately cover and transfer to the preheated oven. Cook for about 5 - 6 hours, until the meat is tender.
Mix together the coriander, white onion, lime and salt. Remove the meat from the sauce and shred using two forks. Ladle the broth into a bowl and add a handful of chopped coriander
Add a non-stick skillet over medium heat. Dip the tortilla into the top of the broth and add it to the skillet. Pan fry on one side for about 30 seconds and then flip over. Add a some of the shredded meat and the shredded cheese. Fold over and cook until pan fried on both sides, about 1 minute. Transfer to a plate and serve alongside the broth.
