Sardinian Grilled Trattalia with Mediterranean Salad | Trattalia Arrosto Rivisitata con Insalata Mediterranea
Trattalia is what a Sardinian shepherd does with everything left when a lamb has been butchered at home. Liver, heart, lung, kidney and spleen go onto one spit, the bundle is wrapped tightly in the caul fat that lined the animal's abdomen, and it stands beside an open fire until the fat has melted away and the outside is dark and crisp.
This version changes one thing only: what arrives beside it. The spit is built exactly as it has always been built, because there is no improving on it. Next to it goes a cold Mediterranean salad of tomato, cucumber, celery, red onion, olives, capers and mint, and its job is purely technical. Offal roasted inside caul fat becomes tiring by the fourth mouthful, and acidity and cold crunch reset the palate between them.
The reimagining is therefore a matter of balance rather than technique. The trattalia is cut, threaded and roasted as the shepherds do it, beside embers rather than over flame, turned by hand, basted by its own melting fat. Together, the two halves are why this way of cooking offal has outlived the slaughter that produced it.

The Story
Trattalia, spelled trattaglia in parts of the island, belongs to the pastoral interior of Sardinia and to the day of the slaughter. When a lamb or kid was killed at home the carcass went to market or into the salt, but the offal could not wait: liver, heart, lungs, kidneys and spleen spoil within hours in a warm climate. The answer was a spit and a fire, and the dish was eaten by the people who had done the butchering, standing up, with bread and a glass of something rough.
It is a dish of Easter and of the autumn slaughter above all, the moments when young lamb and kid are killed, and it appears at village festivals across the Campidano, the Marmilla, the Barbagia and the Sulcis. The spit is usually cut from myrtle or lentisk, which perfumes the meat faintly as it heats, and the fire is built from the same maquis scrub. It stands upright beside the embers rather than over them, so the fat drips onto the ground and not into flame, which would smoke the whole thing bitter.
Sardinian butchery produces two related spits that are constantly confused. Cordula is made from the intestines, cleaned and plaited into a thick braid. Trattalia is the organ spit, and its binding is the caul: the lacy sheet of fat from the peritoneum, the membrane wrapping the abdominal organs, which Sardinians call rete. Neither is a variant of the other and neither is a leftover. What has changed is only the supply. Household slaughter is now rare and regulated, so trattalia has moved to the butcher's counter and the caul has become the hard ingredient to find rather than the free one.

Preparation
Soaking and trimming the offal
Soak the liver, kidneys and spleen in the milk for 1 hour in the refrigerator, which draws out blood and softens the metallic edge raw kidney carries. Meanwhile split the heart and cut out the valves, the white tendon and any clotted blood. Peel the membrane off the liver, skin the kidneys, and cut the lung from the bronchial tubes, which never become tender. Pat everything dry.
Softening the caul fat
Put the caul in lukewarm water, about 95°F (35°C), with a spoonful of vinegar, for 20 minutes. Cold caul is brittle and tears the moment you pull on it; warmed through it turns slack and elastic. Float it in a second bowl of clean warm water and unfold it there rather than on a board, letting the water carry the weight.
Cutting the pieces to their own cooking times
This cut decides whether the spit works. Liver cooks in minutes and turns to grit past that, so cut it large, about 2 inches (5 cm), to slow it down. Heart and lung need far longer, so cut them small, about 1 inch (2.5 cm), with kidney and spleen between at 1 1/2 inches (4 cm).
Threading the spit in order
Thread the pieces onto a long metal skewer or a trimmed myrtle branch in a deliberate order. Heart and lung go in the middle, the hottest stretch, kidney and spleen flank them, and liver goes at the two ends, the coolest positions. Slide in a bay leaf every fourth piece and push the pieces together without compressing them.
Wrapping in the rete
Season the loaded spit all over with the coarse salt and pepper and brush it lightly with oil. Lay the caul flat, set the spit along one edge and roll it so the sheet goes round two or three times, overlapping itself. Tuck the ends in and tie it with twine wherever it is loose: the wrap must be continuous, since any exposed piece dries out.
Building the fire
Burn down hardwood, ideally olive, myrtle or lentisk, to a deep bed of grey embers with no flame at all. Rake them into a ridge and stand the spit at a steep angle beside them, about 8 inches (20 cm) away, never above. That is the point of the method: the melting caul drips onto bare ground, so nothing flares or tastes of smoke.
Roasting in the fat of the caul
Give the spit a quarter turn every 5 minutes for 40 to 50 minutes. For the first quarter of an hour almost nothing appears to happen, then the caul renders and the surface glazes and darkens. Do not baste: the caul is the baste, and every turn moves its melting fat onto a new face. It is ready when a skewer in the central heart meets no resistance.
Dressing the salad and resting the spit
In the last 10 minutes cut the tomatoes into wedges, the cucumber into half moons, the celery into thin slices and the onion into fine petals. Combine with the olives, rinsed capers, torn mint and parsley, dress with vinegar, then salt, then oil, and toss once. Rest the spit 10 minutes off the heat: residual heat finishes the liver.
Plating
Cut the spit into lengths of about 2 1/2 inches (6 cm) with a heavy knife and one decisive stroke, so the crisp crust does not shatter and slide off. Do not pull the offal off the skewer and pile it up: the bundle held together by its own rendered caul is what the diner should recognise.
Use a warm plate, around 130°F (55°C), and set two or three cut lengths slightly apart rather than stacked, so each keeps its crust dry. Spoon the cold salad in a loose heap to one side, never over the top, because its vinegar softens the crust within a minute.
Finish with flaked salt over the offal only, a thread of oil over the salad only, and one lemon wedge on the rim. The lemon belongs at the table rather than in the kitchen: the squeeze is the diner's decision, and offal takes acidity differently from one palate to another.
Professional Technique
The first of the two techniques that carry this dish is the rete, the caul fat. Caul is the omentum, a lacy apron of fat hanging over the abdominal organs, roughly nine parts fat to one part connective tissue. Wrapped round the spit it performs two contradictory jobs at once. It is a barrier, shielding lean offal from the radiant heat of the embers for the first quarter of an hour, and a source of fat, melting slowly and bathing the pieces from outside for the rest of the cooking. No basting liquid can do that: a liquid runs off in seconds, while the caul releases fat gradually over forty minutes from exactly the position where it is needed. By the end it has almost vanished, white lace turned into a thin dark crust fused to the surface. That is why it goes into lukewarm water first: cold, the fat is set hard, the membrane snaps instead of stretching, and gaps dry the offal beneath.
The second technique is running four cooking times on one spit, solved with geometry rather than heat. Liver is fine grained and essentially cooked at 145°F (63°C); beyond that it goes chalky and irreversibly dry. Heart is worked muscle with real collagen, lung a sponge of elastic tissue, and both want three or four times as long. On a grill that is impossible. On a spit there are two variables. The first is size: liver cut large so heat takes longer to reach its centre, heart and lung cut small so it arrives quickly. The second is position, because a spit beside a ridge of embers is hottest at its middle and cooler at both ends. Heart and lung take the hot middle, liver the cool extremities, kidney and spleen the gradient between.
Texture and Moisture Control
Three textures must arrive together: a crisp exterior, liver still faintly pink at the centre, heart and lung tender rather than rubbery. The crust is the easiest to get and to lose. It forms because the rendering caul fries the surface in its own fat, and it survives only in dry air, so the spit rests uncovered and never in foil.
Moisture inside the pieces is governed by temperature rather than time. Liver holds its moisture to about 145°F (63°C) and then loses it fast as its proteins tighten, which is why the rest matters: residual heat carries the large end pieces those last degrees off the fire, where the rise is slow. Heart needs roughly 165°F (74°C) for its collagen to soften into gelatin.
The salad has a moisture problem of its own. Salt tomato and cucumber and they weep within minutes, leaving a pool that thins the dressing and runs into the crust. Dress with vinegar and salt first, then add the oil, which coats the surfaces and slows the leaching.
Professional Mise en Place

Chef Tips
Order the caul fat a week ahead and ask for it by name, rete in Italian. Few counters carry it on display and it is sold frozen more often than fresh, though a sheet thawed overnight behaves almost as well. Without it there is no trattalia.
Smell the offal before you cook it. Fresh lamb liver smells sweet and faintly mineral and fresh kidney smells clean; anything ammoniacal is past the point where soaking or hard roasting rescues it.
Do not skip the lung because it looks unfamiliar. It contributes almost no flavour, but it absorbs the caul fat and gives a light spongy texture between the dense pieces. Built from liver and heart alone, the spit eats monotonous.
With no fire, use the rotisserie at 400°F (205°C) and stand a tray of water on the oven floor: not to humidify the meat but to stop the dripping fat smoking in a closed box.
Common Mistakes
Unfolding cold caul fat. Straight from the refrigerator the membrane is brittle and tears into strips. Twenty minutes in water at about 95°F (35°C), then unfolding it while it floats, is the difference between one sheet and a handful of scraps.
Cutting every piece the same size. Uniform cubes guarantee failure, because liver and heart at the same size cannot finish together. Cut the liver large and the heart and lung small, and thread them by position too.
Roasting over the flame instead of beside the embers. Fat dripping into live fire flares and coats the spit in acrid smoke, the commonest way this dish is ruined. Bank the embers aside and stand the spit next to them so the fat falls on bare ground.
Overcooking the liver. Past about 145°F (63°C) it turns chalky and grainy and nothing recovers it. Large end pieces, the coolest positions and a full 10 minute rest are the three defences.
Wrapping the spit in foil to keep it warm. Trapped steam softens the rendered caul into a damp skin and undoes forty minutes of work. Rest it uncovered on a rack somewhere warm and dry.
Wine Pairing
Cannonau di Sardegna DOC: The island's own red and the bottle this dish has always been drunk with. Its tannin is soft rather than grippy, which matters because hard tannin turns metallic against liver, and its dried herb character sits beside the myrtle and bay. Serve it around 61°F (16°C) so the acidity still cuts the fat.
Campidano di Terralba DOC: From the plain where trattalia is most at home, built on Bovale, a lighter and more nervous red than Cannonau. The lower alcohol and brighter fruit keep the palate moving, and its rustic earthiness answers the offal instead of covering it.
Alghero DOC: The Catalan corner of the north west coast, where the reds carry more polish and firmer structure than the island average. That structure is the recommendation: enough grip for the crust and the fat, and enough fruit to survive the vinegar in the salad, which flattens softer reds.
Vermentino di Gallura DOCG: The white answer, and better than it sounds. Grown on decomposed granite, it has a saline bite and a citrus acidity that slices the caul fat cleanly, and a bitter almond finish that runs alongside the mineral edge of the kidney.
Nuragus di Cagliari DOC: The everyday white of the Campidano, light, high in acidity and deliberately neutral, and the neutrality is the point. It refreshes between mouthfuls without adding another flavour to a plate already carrying offal, caul, mint and vinegar. Poured cold and by the carafe at the slaughter.
Storage & Reheating
Trattalia is a dish to eat off the fire: offal deteriorates faster than muscle meat and the rendered crust is gone once it meets moisture. Cooked, cut and sealed airtight it holds 2 days in the refrigerator at most. Never freeze it cooked, because the liver goes mealy and the lung collapses on thawing.
To reheat, lay the pieces cut face down in a dry heavy pan over medium heat for 2 to 3 minutes a side, with no oil. There is enough fat still in them, and direct contact is the only way to bring crispness back.
The salad does not keep once dressed. Undressed cut vegetables hold overnight sealed if the tomato is kept apart. Assemble fresh every time.
