Pork belly rolled around herbs, garlic and fennel, roasted until the skin crackles, sliced thick into a crusty roll. The same idea runs from Rome's porchetta to Philadelphia's roast pork with provolone and greens.
10 crusty rolls (ciriola, ciabatta or seeded Italian)
For Philly style: sharp provolone, broccoli rabe or spinach sautéed with garlic, the pan juices
How to make it
Season (15 min, then overnight): Lay the belly skin side down and score the meat side in a crosshatch. Rub in the fennel, pepper, chili, garlic, herbs, zest and 1 tbsp salt. Roll it up tightly (skin outside) and tie with string every 3 cm. Pat the skin dry, rub with salt, and refrigerate uncovered overnight to dry the skin.
Slow roast (3 1/2 hr): Heat the oven to 150 C (300 F). Roast on a rack in a pan until it reaches 85 C (185 F) inside, 3 to 3 1/2 hours. Add a cup of water to the pan halfway so the juices don't burn.
Crackle (20 to 30 min): Turn the oven to 240 C (465 F) and roast until the skin puffs, blisters and crackles all over, 20 to 30 minutes. Watch it; turn the pan if one side darkens fast.
Rest (20 min): Rest 20 minutes, then cut off the string and slice 1 cm (1/2 in) thick with a serrated knife.
Build: Split the rolls and fill with a few slices and some broken crackling, salted. For Philly roast pork, add provolone and garlicky greens and spoon the pan juices over.
Tips
The drying overnight is what gets the crackling; don't cover it.
Leftovers make the best fried-rice or hash you'll eat this year.
