Step 1: Make the Birria (If Starting from Scratch)

1. Season the Meat: Pat the beef dry with paper towels. Season generously with salt and black pepper on all sides.
2. Sear the Meat: Heat vegetable oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Sear the meat on all sides until browned, about 3-4 minutes per side. Remove the meat and set aside.
3. Prepare the Sauce: In the same pot, sauté the onions and garlic until fragrant and softened, about 3 minutes. Add the dried chilies and toast for 1-2 minutes until fragrant.
4. Blend the Sauce: Transfer the onions, garlic, and chilies to a blender. Add the chipotle peppers, beef broth, cumin, oregano, cinnamon stick, and apple cider vinegar. Blend until smooth.
5. Cook the Birria: Return the meat to the pot and pour the blended sauce over it. Add bay leaves and enough water to cover the meat. Bring to a simmer, then cover and cook on low heat for 3-4 hours, or until the meat is tender and shreds easily. Alternatively, cook in a slow cooker on low for 6-8 hours.
6. Shred the Meat: Remove the meat from the pot and shred it with two forks. Strain the consommé (cooking liquid) to remove solids and set it aside for later.

Step 2: Prepare the Pizza Dough

1. If using homemade dough, prepare it according to your recipe and allow it to rise until ready to use.
2. Preheat your oven to 475°F (245°C) and place a pizza stone or baking sheet inside to heat.

Step 3: Assemble the Pizza

1. Roll Out the Dough: On a floured surface, roll out one pizza dough into a 12-inch circle. Transfer it to a piece of parchment paper for easy handling.
2. Brush with Consommé: Mix ½ cup of birria consommé with 1 tablespoon of olive oil. Brush a generous layer of this mixture over the pizza dough to infuse it with flavor.
3. Add Cheese and Meat: Sprinkle 1 cup of shredded mozzarella cheese evenly over the dough. Distribute ¾ cup of shredded birria meat on top of the cheese.
4. Top with Red Onion: Scatter thinly sliced red onion over the pizza for added crunch and flavor.

Step 4: Bake the Pizza

1. Carefully transfer the parchment paper with the pizza onto the preheated pizza stone or baking sheet. Bake for 12-15 minutes, or until the crust is golden and crispy, the cheese is melted, and the toppings are bubbling.
2. Remove the pizza from the oven and let it cool for 1-2 minutes.

Step 5: Garnish and Serve

1. Sprinkle the baked pizza with fresh cilantro and crumbled queso fresco, if using.
2. Serve with lime wedges on the side for an extra burst of flavor.
3. Repeat the process for the second pizza dough and toppings.
