Sardinian Lamb

Agnello di Sardegna has held IGP protection since 2001. It covers lamb from Sarda-breed sheep born, raised and slaughtered on Sardinia, an island with over three million sheep and the centre of Italian production of Pecorino Romano, Pecorino Sardo and Fiore Sardo.

That context explains the product. The lamb is not the point of the farm, it is the consequence: a ewe must lamb in order to give milk, and the lamb is taken off early because the milk is wanted for cheese. Calendars, slaughter weights and prices all follow from that.

The rules define three categories by carcass weight. Agnello da latte, 5 to 7 kg, fed exclusively on its mother's milk. Agnello leggero, 7 to 10 kg, which has begun to graze. Agnello da taglio, 10 to 13 kg, raised on milk and natural pasture.

Those are carcass weights, not liveweights: a 6 kg milk-fed carcass comes from an animal of roughly thirty to forty days. The meat is pale pink, almost white, with firm white fat.

Mild to the point of surprising people. Milk-fed Sardinian lamb has almost none of the strong, woolly, faintly barnyard character that defines lamb for most British and American eaters, because those compounds build up with age and with a grass diet, and a five-week-old milk-fed animal has not had time to develop them.

What is left is delicate, sweet and clean, closer to very good veal or rabbit than to a leg of hogget. The texture is soft and fine-grained, and the fat is mild rather than tallowy.

The heavier categories move along the scale. Agnello leggero and agnello da taglio have grazed, and they pick up a gentle grassy edge, more colour and more chew: still far milder than a six-month lamb, but with actual lamb character.

Roasted over wood with myrtle branches, the meat takes on a resinous, slightly bitter perfume that is the signature of Sardinian cooking and does not exist anywhere else.

Roast it fast and season it lightly. Milk-fed lamb has very little fat and almost no collagen, so long cooking dries it out, the opposite of what a shoulder of ordinary lamb wants. Salt, olive oil, maybe rosemary or a myrtle branch, a hot oven, and take it out when the juices still run pink at the bone.

Spit-roasting over wood embers is the island's own method, and the one that justifies buying a whole animal.

Agnello con i carciofi is the Easter dish: brown the pieces, add spiny Sardinian artichokes, white wine and parsley, and in some versions finish with beaten egg and lemon. Su succhittu, from the Barbagia, stews the lamb in a sauce thickened with bread, garlic and pecorino. Cordula, a plait of offal wrapped in intestine, grilled or cooked with peas, is the most local preparation and the hardest to find off the island.

Chops go straight on the embers, two minutes a side, and are eaten with your hands. The heavier categories, having grazed, take a slow oven far better and are the ones to buy for a braise.

Fresh cuts keep two to three days in the coldest part of the fridge, covered but not pressed tight under cling film, since trapped moisture makes the surface slippery and grey at the edges. A whole quarter under vacuum runs to eight or ten days on the date the butcher gives it. What changes over those days is water: the surface dries and darkens, the flesh firms, and any exposed fat picks up fridge smells. Beyond that window the date on the pack and the butcher who sold it are the reference.

It freezes better than most meat, because young lamb is lean and low in connective tissue. Portion it first, chops, shoulder, leg, into separate bags, and reckon on six months. Thaw in the fridge, twenty four hours for a large piece: at room temperature the outside warms long before the centre and the meat sheds liquid onto the plate. Roast leftovers hold a couple of days and reheat poorly whole, which is why the Sardinian answer is to bone them, cut them small and fry them with potatoes.

The Agnello di Sardegna IGP mark is stamped on the carcass and carried onto the label of packed cuts along with the abattoir code, and it is the only reference that means anything, because the phrase Sardinian lamb on its own is not protected. The colour is a very pale pink, close to white in the milk fed grades, darkening in the heavier ones. The fat is bright white, firm and dry. Red flesh or fat turning yellow belongs to an older animal.

Raw, it barely smells of anything, and that is the sharpest difference from the lamb most British and American shops sell. New Zealand, Australian and British lamb carries a woolly, pungent smell you can identify across a room, produced by compounds that build up with age and grass feeding, and in an animal a month old they have not had time to form. Size tells the same story: a hind quarter of Sardinian milk lamb weighs barely a kilo and a half, so a four kilo leg is something else. The nearest thing abroad is Spanish lechazo, or milk fed lamb from a specialist butcher.

Very little Sardinian lamb leaves Italy. There is no meaningful export chain to the US or UK, and what is sold abroad as Italian lamb usually is not IGP-certified. If you want the milk-fed style outside Italy, look for Spanish lechazo, French agneau de lait or a domestic butcher who can source genuinely young lamb.

In Italy, buy it at a butcher's counter rather than a supermarket, by the quarter or as a whole carcass. Expect 14 to 22 euros a kilo, rising to 25 or 30 in the weeks before Easter and Christmas when national demand peaks. Packaged chops in supermarkets run 28 to 35 euros a kilo.

Check for the Agnello di Sardegna IGP mark, stamped on the carcass and printed on packaged cuts with the abattoir code. The phrase 'Sardinian lamb' on its own is not protected.

Size is the quickest sanity check. A hind quarter of milk-fed Sardinian lamb weighs well under two kilos; anything the size of a four-kilo leg is a different animal.

The Barbagia, the mountainous interior around Nuoro, is where this is best understood. Orgosolo, Oliena, Mamoiada and Fonni still spit-roast whole lambs over wood at village feasts and in agriturismi, and cordula appears on menus without having to be ordered in advance.

Ogliastra, on the east coast between Tortoli, Ulassai and Baunei, and the Sarcidano around Laconi have the same tradition with fewer visitors. In the Marmilla and the Campidano, lamb comes with artichokes and broad beans more often than on a spit.

In Cagliari, the San Benedetto market is the place to look at the cuts and ask where they came from. Sassari and Oristano butchers work almost exclusively local lamb.

The season decides the trip: December to April, with Easter as the week when the whole island cooks the same thing. Come in summer and there is lamb, but less of it and dearer.
