Ingredients

1 piece (4 pounds) meaty slab bacon or pork belly, rinsed and pat dry

18 dried Andean panca peppers or a combination of equal parts dried mirasol and panca peppers (or a combination of Mexican dried ancho and guajillo chiles), stemmed and seeded

1 tablespoon extra-virgin olive oil

8 large cloves garlic

2 teaspoons ground cumin

1 teaspoon dried oregano

1/4 teaspoon aniseed

1/2 teaspoon Spanish hot paprika

1/2 cup freshly squeezed orange juice

1/2 cup freshly squeezed bitter orange juice, such as from Seville oranges, or 1/4 cup freshly squeezed lime juice

2 tablespoons guava preserve or 1 tablespoon Catalan wild oak honey

1/4 cup Oloroso sherry

1/2 cup grated brown loaf sugar, preferably Mexican piloncillo or Columbian panela or dark muscovado sugar

1 teaspoon coarse salt

Guatemalan Red Cabbage Relish, optional

Mendoza’s Fresh Corn Polenta, optional

Cacao nibs, optional

Preparation

Score the slab bacon on the meat side; set aside.

Heat a heavy-bottomed skillet over medium heat. Working in batches, add dried peppers to skillet and toast lightly for 3 to 4 seconds on each side. Transfer toasted chiles to a medium bowl. Cover with hot water and let stand until soft, about 10 to 15 minutes.

Transfer peppers to the jar of a blender or bowl of a food processor, along with olive oil, garlic, cumin, oregano, aniseed, paprika, orange juices, guava preserves or honey, sherry, brown loaf sugar, and salt; blend until smooth.

Place bacon in a 2-inch deep baking pan. Pour the chile mixture over bacon and rub thoroughly until fully coated. Cover with plastic wrap and let marinate at least 6 hours and up to overnight.

Preheat oven to 350 degrees with rack in the center. Remove plastic wrap from baking dish and add 1/4 cup water to dish. Cover baking dish tightly with parchment paper-lined aluminum foil. Transfer baking dish to oven and bake for 1 hour. Continue baking and basting bacon, until golden brown and fork tender, about 20 minutes more.

Transfer bacon to a large cutting board and cut into 2 1/2-inch pieces. Serve immediately with Guatemalan red cabbage relish or Mendoza’s fresh corn polenta; garnish with cacao nibs, if desired.
