Birria de Res recipe

20 cups water
2 pounds beef bones
5 pounds chuck roast (diezmillo en trozo)
10 guajillo chiles
1 large onion
1 head garlic
10 medium bay leaves
10 carrots, peeled and quartered
3 tablespoons chicken bouillon
1 tablespoon salt
4 dry guajillo chiles
2 bay leaves
dried hot chiles (such as chile de arbol, pequin, puya or cayenne pepper)
1 cup canola oil
1/2 teaspoon garlic powder
1/2 teaspoon ground black pepper
1/4 teaspoon ground clove
1/2 tablespoon chicken bouillon
1/4 teaspoon sugar
1/2 tablespoon Mexican oregano
corn tortillas
birria broth
chile oil
1 cup shredded mozzarella, queso Oaxaca or Mexican cheese blend
shredded beef
chopped onions
shredded cabbage (optional)

For the Birria:
Bring water to a boil in a large Dutch oven and add beef bones, chuck roast, chiles, onion, garlic, bay leaves, carrots, chicken bouillon and salt. Boil for 15 minutes on medium heat. After 15 minutes, skim impurities from the broth. Continue to boil for 1 hour.
After 1 hour, remove chiles and 1 cup broth and blend until smooth.
Add blended ingredients to broth and continue to cook for about 2 hours on medium-low heat, until the meat is fork-tender and pulls apart easily.
Remove roast, place on a cutting board and shred.

For the Chile Oil:
Break up dry guajillo chiles and bay leaves and add to spice grinder or coffee grinder. Add hot chiles. Grind them into a powder.
Heat a pot on medium. Bring the oil to somewhere between 290 and 310 F, using a thermometer to check the temperature. If you don’t have a thermometer, you’ll know the oil is ready when you dip a wooden spoon in the oil and start seeing light bubbles. If the oil is smoking, it is too hot and the spices will burn.
Turn off the heat. Add chile blend and stir into oil. Add garlic powder, black pepper, ground cloves, bouillon, sugar and oregano, and mix. Let oil cool. Once completely cooled, transfer to a storage container. Store at room temperature.

To assemble:
Heat pan or griddle on medium.
Dip a corn tortilla in the birria broth and then the chile oil.
Place the corn tortilla in the heated pan. Add cheese, shredded beef, onion, cilantro and optional cabbage. Fold the tortilla over into a taco shape. Cook 2 minutes on each side, or until you achieve the desired crispness.

To serve:
Ladle birria broth into a cup and serve alongside taco. Dip the taco into the birria and alternate between taking bites of the taco and sips of the birria.
