Roast Pork with Crispy Skin

 Toast fennel seeds, pink peppercorns, and red pepper flakes in a dry frying pan over low heat. Grind toasted spices in a coffee grinder or pound using a mortar and pestle. Transfer to a small bowl. Add sage or basil, rosemary, and garlic. Set aside.

Poke the skin of the pork belly all over using a paring knife. Turn it over and score the flesh in a diamond pattern. Liberally rub the belly and pork loin with salt. Rub both belly and loin with the prepared spice mixture.

Place the pork loin in the center of the belly. Roll the belly and secure tightly with kitchen twine. Wrap with foil or plastic wrap and leave in the refrigerator overnight.

Preheat oven at 300°F. Remove foil or plastic wrap. Place pork on a wire rack set on a baking sheet or roasting pan. Roast for about 1 1/2 hours or until the internal temperature of the roast registers 150°F on a meat thermometer.

Increase heat to 500°F and continue roasting until skin is crisp and blistered, about 20 more minutes. Let rest for 10 minutes at room temperature before slicing.
