Score the Skin & Make the Paste
10 Mins
Room temperature, ~20°C (68°F)
Pat the belly skin completely dry with paper towels and score it in a diamond pattern, cutting through the skin and fat but not into the meat. Mix the garlic, rosemary, fennel seeds, salt, pepper and olive oil into a coarse paste.
A dry skin scores cleanly — if the knife skips, dry the skin again.
Done when: Even diamond cuts across the whole skin; a fragrant green herb paste.

Stuff, Roll & Tie
15 Mins
Room temperature, ~20°C (68°F)
Lay the belly skin-side down and spread the herb paste over the meat. Place the loin along one long edge, roll the belly tightly around it, and tie with kitchen string every 4 cm, pulling each loop snug. Rub the outside with a little more salt.
Roll away from you and keep the loin centred so every slice has meat in the middle.
Done when: A firm, even cylinder with the skin smooth on the outside.

Rest Overnight
12 Hours
Fridge, 4°C (39°F)
Set the roll on a rack over a tray and refrigerate uncovered overnight. The cold, dry air dries the skin, which is essential for crackling.
Do not cover the roll — trapped moisture is the enemy of crisp skin.
Done when: Skin dry and papery to the touch the next day.

Slow Roast
3 Hours
Oven, 160°C (325°F)
Heat the oven to 160°C (325°F). Place the roll on a rack in a roasting tin and roast for about 3 hours, until the meat is tender and the centre reaches at least 63°C (145°F) — aim for about 71°C (160°F) for a juicy, sliceable roast.
Put a little water in the tin to stop the dripping fat smoking.
Done when: Meat tender, fat rendered, skin starting to firm and colour.

Blast for Crackling
30 Mins
Oven, 220°C (425°F)
Turn the oven up to 220°C (425°F) and roast for 25–30 minutes more, until the skin is deep golden, blistered and crisp all over. Watch it closely in the last 5 minutes — crackling can go from perfect to burnt quickly.
If one patch lags behind, turn the tin so it faces the hotter side of the oven.
Done when: Skin puffed, blistered and shattering-crisp; centre at 71°C (160°F) or above.

Rest & Slice
20 Mins
Resting, ~70°C (158°F)
Rest the porchetta for 20 minutes before slicing, so the juices settle. Cut off the string and slice thickly, about 2 cm per slice, so each serving has crackling, belly and loin.
Use a long, sharp knife and saw gently — pressing down crushes the crackling.
Done when: Thick slices showing the spiral of belly, herbs and loin, with crisp skin on top.
