Sa Trattalia

Sa Trattalia originates in Ogliastra, the mountainous eastern region of Sardinia, though the preparation is diffused across the whole island under many dialect names. It grew from the pastoral principle of wasting nothing of a slaughtered animal: when a lamb or kid was killed, its pluck became this dish. In shepherd families it is tied to the great religious and secular feasts, above all Christmas. The offal is cleaned with water and vinegar, threaded onto a spit alternating with lard and bread, then wrapped in the peritoneum and the coiled small intestine, the compact casing called sa nappa in Sardinian. Cooking proceeds in two stages over embers, first searing the meat rare, then crisping the casing over one and a half to two hours. It is registered by the Italian Ministry of Agriculture among the Traditional Agri-food Products of Sardinia, and differs from cordula, which uses the pluck of older, weaned animals and, in the corda variant, the stomach and belly of sheep or goat.

The sliced rounds shatter at the edge into a brittle, smoky casing of crisped intestine and caul, giving way to a soft, rich interior where the liver turns creamy, the heart stays firm and springy, and lung and spleen melt into a mineral, faintly bitter tenderness bound by the sweetness of rendered lard.

The caul and intestine casing is the engine of the dish. Rich in collagen and fat, it renders slowly over the embers, basting the enclosed organs from within while its own surface dehydrates and browns through the Maillard reaction into the brittle amber crust. Wrapping the pluck tightly traps steam and rendered fat inside the cylinder, so the delicate liver and lung braise gently in their own moisture rather than drying out. The two-stage cooking is deliberate: a first searing sets the exterior and drives off surface water, and the long, low finish of one and a half to two hours gives the collagen time to convert to gelatin and the casing time to crisp without scorching the interior.
