Italian Sardinian Spit Roasted Suckling Pig | Porceddu Arrosto
Porceddu is a fire, a stick and salt. No marinade, no rub, no stuffing, no oven. A milk fed pig is opened flat, run onto a wooden spit, planted at an angle beside a bed of embers and turned slowly for three or four hours while the fat renders and the skin dries to glass.
The wood is the only seasoning Sardinia allows itself. Myrtle, lentisk and corbezzolo, the strawberry tree, give off a resinous, faintly bitter smoke, and that smoke is what separates a porceddu from a suckling pig roasted anywhere else. Oak and olive hold the heat; the aromatic branches go on last.
The measure of a porceddu is the skin. It should shatter under a knife like a sheet of caramel and be heard across the table, with the meat under it still pale and wet. Getting both at once is solved by distance and patience rather than temperature: the pig sits far from the fire for most of the cooking and comes close only at the end.
Yield: 8 to 10 servings. Prep: 30 minutes. Dry in the air: 12 hours. Cook: 3 hours 30 minutes. Rest under myrtle: 30 minutes. Difficulty: advanced. Course: main course. Region: Sardinia, the Barbagia and the Campidano.
The Story
Porceddu, porcheddu in the Logudorese north, belongs to the shepherds. It is the food of men who spent the season away from the village with the flock and cooked over the fire they already needed for warmth, and its plainness is circumstance rather than modesty. A pig, a spit of wild olive, coarse salt and whatever scrub was burning: nothing in it needs a kitchen, a pot or a market, which is why it has not changed.
The most famous version of it was never a recipe at all. A carraxiu means buried: the way a stolen animal was cooked without a visible fire, in a pit lined with hot stones and myrtle branches, covered with more myrtle and earth and left for hours while the shepherds stood somewhere else. It survives as a delicacy and as a story about a Sardinia of banditry: the myrtle scent that gives the meat its character was first a way of hiding the smell of cooking.
Today it is festival food. It turns for weddings, for the sagre of the inland villages, for Sant Efisio in May, and it is still carried to the table on a plank of cork or a bed of myrtle rather than on a plate. The pigs come from the Barbagia and the Ogliastra, weigh 9 to 13 lb (4 to 6 kg) and are killed at four to six weeks, before they have eaten anything but milk. That is what makes the fat sweet and the meat pale.

Preparation
Drying the skin overnight
Ask the butcher for the pig cleaned, head on, opened flat along the belly. Wipe the skin dry, rub the cavity with half the coarse salt and leave the skin bare. Set it skin side up on a rack, uncovered, in the coldest place you have, for 12 hours. Skin that goes to the fire damp blisters and softens instead of turning to glass, and no heat later corrects that.
Building the fire
Burn oak or olive down to a deep bed of embers, about 45 minutes. You want a light ash coat and no flame at all, since flame scorches the skin in seconds and leaves the meat raw. Rake the embers into a long low bank. The pig stands beside it, never over it, fed from a second fire alongside.
Spitting the pig
Run the spit in beside the backbone from the hind end through to the mouth, so the weight sits on the wood rather than hanging from it. Tie the legs with wire or soaked cord so nothing swings. Wood matters: metal conducts heat into the loin and overcooks it from the inside long before the skin is ready.
Setting the distance
Plant the spit at an angle in the forked stakes, skin side towards the embers, 16 to 20 inches (40 to 50 cm) away. Hold your palm where the skin sits: you should be able to keep it there six or seven seconds. If not, move the pig back rather than rake the embers away. This distance is the most important decision of the whole cooking.
Turning through the long phase
Turn the spit a quarter turn every 15 minutes for the first 2 hours 30 minutes, keeping the distance and feeding the bank so the heat never drops. Fat starts to run within the first half hour and should drip steadily but never catch fire; if a flare starts, move the pig back at once. Do not salt or baste the skin yet, since both hold moisture at the surface.
Perfuming with myrtle
About an hour before the end, lay green myrtle branches onto the embers and let them smoulder, with lentisk or corbezzolo if you have them. The skin is dry by now and takes the resinous smoke instead of steaming under it. From here, brush it lightly with soft lard on the myrtle brush every 20 minutes. Lard, not oil: it is the same fat as the animal and it fries the surface rather than wetting it.
Crisping and reading the temperature
For the last 30 to 40 minutes, move the spit in to about 10 inches (25 cm) and turn every 5 minutes, watching the skin go from straw to deep amber. Scatter the last of the salt over it now. It is done when the thickest part of the shoulder reads 165°F (74°C) and the skin taps hard and hollow, which takes 3 hours 15 minutes to 3 hours 45 minutes for an 11 lb (5 kg) animal.
Resting under myrtle
Lift the pig onto a bed of fresh myrtle laid on a plank, cover it with a second layer of branches and leave it 30 minutes in a warm place. This is not only a rest: the trapped steam pulls myrtle oil into the meat, and it is what makes a porceddu smell the way it does. Never use foil, which traps water against the skin and undoes three hours of work in ten minutes.
Plating
Porceddu is carved at the table, with a heavy knife and a firm hand. Set the pig on the myrtle it rested on, on a plank of cork or untreated wood, and bring the whole thing out before anything is cut. Half the dish is the sound the skin makes and the smell off the disturbed branches.
Cut down the spine first, then across into sections that keep skin attached to meat: shoulder, loin, belly and leg. Nobody gets meat without skin, and nobody gets skin alone. Use warm plates, never hot ones, since a hot plate makes each piece sweat underneath and softens the crust from below.
Alongside goes pane carasau and nothing else. No sauce, no gravy, no vegetables, no lemon. The rendered fat is not served: this is a dry roast, and its point is a contrast between crust and pale meat that any liquid destroys.
Professional Technique
The technique is radiant heat at a controlled distance, which behaves nothing like an oven. In an oven the air carries the heat and surface and interior rise together. Beside an ember bank the energy arrives as infrared, is absorbed almost entirely by the skin, and falls away with the square of the distance. That is why 16 inches and 10 inches give completely different results from one fire, and why the cook moves the pig rather than the fuel.
The angled spit is doing something specific. A tilt makes rendered fat run down the skin and off the low end instead of pooling in the cavity, so the skin meets hot moving fat rather than sitting in liquid. It also lets the thick shoulder sit closer to the embers than the thin loin, which is the only practical way to make two very different thicknesses finish together.
The myrtle is applied in two forms and neither is a garnish. Green branches on the embers release aromatic oils as smoke, which deposits on dry skin and would run off a wet one, so the order matters. The rest under fresh branches works by steam: the pig is still hot enough to drive moisture out of the leaves, and that vapour carries myrtle oil into the meat.
Texture and Moisture Control
Crisp pig skin is a dehydration problem before it is a browning one. Skin is roughly two thirds water bound in collagen and cannot pass 212°F (100°C) or take colour until that water has gone. The overnight drying removes the free surface water, the long phase beside the embers drives out the bound water, and only then can the skin puff and set. Rush either and you get leather.
The meat has the opposite problem. A milk fed pig has very little connective tissue and almost no intramuscular fat, so it behaves more like poultry than pork shoulder and dries fast above 170°F (77°C). The fat layer under the skin bastes the muscle from the inside as it renders, which is why a trimmed pig cooks out dry however carefully it is turned. Pull it at 165°F (74°C) and let carryover finish it.
Fat management is the third axis. Rendered fat must leave continuously, and the moment it pools or ignites the balance breaks both ways: flame scorches the crust and steam from burning fat softens it. The angled spit, the ember bank set to the side and the quarter turn every fifteen minutes all exist for that reason.

Chef Tips
Buy the animal by age rather than weight. A true porceddu has eaten nothing but milk: four to six weeks, 9 to 13 lb (4 to 6 kg). A pig of 20 lb has started on solid feed, and its pink meat and thicker skin will not give the same result on the same fire.
If you have no fire, the honest domestic version is a low oven then a blast. Roast the flattened pig skin side up at 285°F (140°C) for about 3 hours, then raise it to 480°F (250°C) for 20 to 25 minutes, brushing with lard twice. Rest it under myrtle as above. It is very good, and it is not porceddu, because the smoke is missing.
Never let water near the skin. Do not rinse the pig after drying, do not put a tray of water in the oven, do not cover it while it cooks. Sardinian cooks will not even salt the skin until the final half hour, since salt draws moisture to the surface exactly when you are trying to remove it.
Cut the myrtle the morning you cook. Branches that have sat a week have lost their volatile oil and give woodsmoke rather than perfume. If myrtle is impossible, young bay branches are the nearest thing, though sweeter, so use half as much.
Common Mistakes
Cooking over flame instead of embers. Flame scorches the skin in seconds and leaves the shoulder raw underneath, and the burnt patches never recover. Burn the wood down completely, rake the embers into a bank beside the pig, and keep a second fire going.
Starting too close. A pig set 10 inches from the embers at the start has a dark tight skin within twenty minutes and an hour of raw meat inside. Start at 16 to 20 inches (40 to 50 cm) and come in only at the end. The same goes for size: anything over about 15 lb has been weaned and will never give glass skin and pale flesh.
Skipping the overnight drying. Damp skin steams, blisters and goes rubbery, and that is decided the night before rather than fixed at the fire. Leave it uncovered on a rack for 12 hours.
Salting or basting too early. Both put moisture on a surface you are trying to dehydrate. Salt the cavity at the start, salt the skin in the last half hour, and bring out the lard brush only once the skin is dry and the myrtle is on the embers.
Wrapping it in foil to rest. Foil traps steam directly against the crust and softens it completely within ten minutes. Rest the pig on and under fresh myrtle branches, uncovered by anything else, in a warm place.
Wine Pairing
Cannonau di Sardegna DOC: The island red and the bottle actually poured at these tables. Grenache grown on Sardinian heat gives soft tannin, warm red fruit and a dried scrub character that sits directly on the myrtle smoke. Its moderate acidity and generous alcohol handle the rendered fat without the pairing becoming a contest. Serve it at 61°F (16°C), young and unoaked.
Campidano di Terralba DOC: Made from Bovale on the plains south of Oristano, and sharper than Cannonau. Higher acidity and a firmer tannic edge are exactly what you want against the crackling and the sweet milk fed fat. It is a rustic wine that has never pretended otherwise, and it is at its best with plain roast meat.
Alghero DOC: From the Catalan northwest, where the reds have more structure and often see wood. A red Alghero has darker fruit and a firmer frame than anything else here, so it suits the shoulder and belly rather than the loin. Its tannin cuts the fat cleanly and the oak picks up the resinous smoke.
Vermentino di Gallura DOCG: The white answer, and better with roast pork than most people expect. Grown on decomposed granite in the north, it has a saline bite and a citrus acidity that scours the fat between mouthfuls, and a bitter almond finish that runs alongside the smoke. Served cold, around 50°F (10°C), it resets the palate in a way none of the reds can.
Nuragus di Cagliari DOC: The light everyday white of the Campidano plains: high acidity, low alcohol, deliberately neutral. That neutrality is its argument, because a porceddu tastes of pork and wood and nothing else, and this refreshes without adding a third flavour. It is what gets drunk by the litre at village sagre.
Storage & Reheating
Carve only what will be eaten and keep the rest in large pieces, since cut surfaces dry fast. Wrap loosely in paper rather than plastic and refrigerate for up to 3 days. Never seal it in an airtight container while it is warm: the trapped steam softens the skin and it will not come back.
To reheat, set the pieces skin side up on a rack over a tray in a 400°F (200°C) oven for 10 to 12 minutes. The rack matters, since anything flat steams its own underside. Do not cover them, do not add liquid, do not use a microwave. The skin will not be what it was but it will crack again.
It freezes for up to 2 months in large pieces, wrapped tightly, though the skin is lost. Thaw overnight in the refrigerator and treat the meat as a different ingredient: pulled off the bone it is excellent in culurgiones, in a ragù for malloreddus, or chopped cold onto pane carasau.
