Authentic Mexican birria tacos, Jalisco-style, made with braised beef roasted in a fragrant 3-chile sauce with a delicious spice mix. Fill a pot with water and bring to a boil. Add guajillo, ancho, and arbol chile peppers; boil for 5 minutes.
Birria is made with lamb meat or beef. Most often, rib meat is what is used from the lamb, and the shank for beef, but you can use other cuts as well. You start by marinating the meat in a combination of guajillo, ancho, and chipotle peppers. You will also use spices, such as cumin, thyme, oregano, marjoram, and cloves.
· Dried chile peppers: The flavorful birria starts with dried guajillo chile peppers, chile de arbol peppers, and ancho chiles. For a bit of extra heat, don't remove all the seeds.
Bake in the preheated oven, basting meat every 45 minutes with sauce, until birria begins to fall apart, 3 to 4 hours. Remove the lid and bake, uncovered, until birria is crispy on top, about 20 minutes. Remove from oven, cover with 2 layers of aluminum foil, and allow to rest in a warm area for 10 minutes.
