Directions

1. Preheat oven to 325 degrees F.
2. Meanwhile, in a small bowl, combine garlic, paprika, coriander, salt and pepper. Butterfly the pork belly so it’ll open like a book. Spread some of the spice blend over the inside of the belly, then arrange the shoulder on top, trimming it as necessary to cover half of the belly. Spread some spice mixture on the shoulder meat, then fold the belly closed over the shoulder. Spread remaining spice mixture on the outsides of the belly. Cut the belly/shoulder sandwich in half, creating 2 approximately 6-inch pieces of layered pork.
3. In a large skillet over high heat, cook the belly/shoulder pieces until well-seared, 1 1/2 to 2 minutes per side. Transfer to an 8x8-inch baking pan, sprinkle with salt and pepper, and cover tightly with foil. Bake until the internal temperature of the pork reaches 195 degrees F., about 2 1/2 hours. Remove pork from the pan and set aside to cool to room temperature, then transfer to the refrigerator and chill at least overnight, or as long as 2 days.
