- 1/4 teaspoon ground black pepper
- 4 dried guajillo chiles

- 4 tablespoon cider vinegar
- 1/4 cup chopped cilantro
- Place the onion in a bowl over a larger bowl of ice water. In a small pan, combine the vinegar, sugar, salt, and water and bring to a boil. Pour over the onion and let sit until they cool. Drain and store in the refrigerator for a few days.
- Soak the beans in water overnight in the refrigerator. Drain, place in a large saucepan, cover with water, and bring to a boil over high heat. Reduce the heat to a simmer, and cook until tender, about 1 hour.
- Heat the olive oil in a sauté pan over medium heat. Sauté the onion, bell pepper, and garlic until soft. Add the salt, pepper, oregano, cumin, bay leaves, sherry, and sherry vinegar. Bring to a boil, add the beans to the mixture and simmer for about 20 minutes, stirring gently. Pour half of the mixture into a blender and purée. Then, pour back into the beans, and season with salt and pepper, to taste.
- In a bowl, mix all of the ingredients together and set aside.
- In a large bowl, mix the pork butt with the garlic, onion, salt, chili powder, smoked paprika, cumin, cinnamon, and black pepper. Using an electric stand mixer with a grinder attachment, grind the pork with the spices 2 times.
- In a skillet over high heat, toast the dried guajillo and ancho chiles on both sides for a few seconds. Cover the chiles in warm water and soak for 1 hour. After an hour, remove the chiles from the water, and remove the stems and seeds from the chiles.
- Chop the chiles and place them in a blender with the vinegar. Purée until smooth. Combine the spiced pork with the purée. Heat a large nonstick skillet over medium-high heat. Cook the pork until cooked through, about 10-12 minutes. Set aside.
- Add the chopped cilantro to the pickled onions. Top a corn tortilla with a spoonful of black beans. Top the black beans with 2 spoonfuls of the chorizo filling then top with the onion-cilantro mix and some avocado relish.
