Birria tacos

Place the guajillo and ancho chilies in a large heat-proof bowl and pour the boiling water over. Soak 45 minutes.

Cut the chuck roast into two inch cubes.

Set a big pot or Dutch oven over medium high heat and add the vegetable oil.

Season the chuck roast and short ribs all over with the salt.

Sear the beef in batches without crowding, about two minutes a side, until it browns and releases from the pan. Set aside to rest.

Dice the carrots and the onion. Slice the garlic.

Add the carrots and onion to the pot and cook, stirring frequently, seven to eight minutes until tender and browned in the beef drippings.

Add the tomatoes, garlic, Mexican oregano and cumin and cook, stirring constantly, two minutes, scraping the caramelized bits off the bottom.

Add the beef broth. Blend the softened chilies with their liquid and add the puree to the pot.

Add the cinnamon stick, bay leaves and the seared beef, and bring to a boil over medium heat.

Reduce to low and simmer three to three and a half hours, until the meat is fork tender and reads 205 to 210F at the thickest point.

Transfer the meat to a dish and pull it apart with two forks.

Let the pot stand so the rendered beef fat floats to the top, and dredge the tortillas through it on both sides.

Heat the oil in a 12 inch cast iron skillet over medium heat and swirl to coat.

Cook a dredged tortilla about 30 seconds, flip, add the cheese and about a quarter cup of shredded beef.

Fold and cook 30 seconds to a minute more until crispy, with visible caramelization and browning.

Serve with diced onions, cilantro, lime wedges, sliced radishes and a bowl of the warm broth for dipping.
