Culurgiones d'Ogliastra — Sardinian Filled Pasta

Combine the semolina and salt in a bowl, then add the lukewarm water gradually, working the mixture until a cohesive dough forms — lukewarm rather than cold water keeps the semolina pliable from the start, so the dough comes together without tearing or crumbling. Turn onto the bench and knead firmly for 8–10 minutes; the dough must be stiffer and less supple than an egg-based pasta dough, feeling smooth and firm, not soft or yielding, because that rigidity is what allows the wheat-ear closure to hold its shape rather than relax open during shaping. Wrap tightly and rest at room temperature for 30 minutes; the dough is ready when it no longer springs back when pressed.

While the dough rests, boil the potatoes in their skins in salted water until completely tender, then drain, peel immediately, and pass through a ricer while still hot — ricing them hot drives off steam freely, so the filling stays light and fluffy rather than turning stodgy and dense as it would if left to cool first. Add the grated Pecorino Sardo, olive oil, and finely chopped fresh mint, then season with salt, remembering that potato requires generous seasoning. The filling must smell clearly and unmistakably of mint, which is the defining flavour of culurgiones and not merely a garnish — taste and correct the salt before setting aside.

Roll the rested dough to a thickness of approximately 2 mm — thin enough to encase the filling without heaviness, yet thick enough to hold the multiple folds of the closure without tearing under the pressure of your fingers. Cut into discs of approximately 8–9 cm diameter. Place approximately 20–25 g of filling in the centre of each disc, leaving a clean border of at least 1.5 cm all around so there is enough dough to grip and pleat without the filling crowding the seam.

This is where the dish lives or dies: fold the disc up and around the filling to bring the two edges together at the top, pinching firmly to form a tight initial seal, then work along the seam from one end to the other, making 15–20 small, even, alternating folds to create the spighe di grano — the wheat-ear closure — pressing each fold firmly against the last so the ridge locks shut rather than merely sitting on top. The finished piece should be plump and leaf-shaped, approximately 8 cm long, with an even herringbone ridge running its full length. A loose or uneven seal will open during cooking and lose the filling entirely into the water; if freezing, arrange on a tray in a single layer until solid before transferring to bags.

Bring a large pot of well-salted water to a full rolling boil, then lower the culurgiones in carefully in batches — cooking in batches keeps the water at a vigorous boil so the pasta moves freely and does not stick or settle on the bottom. Cook for 3–4 minutes; they are done when they float and the pasta at the thickest point of the closure yields to gentle pressure without resistance — firm but not doughy at the centre.

Lift the culurgiones from the water with a slotted spoon and transfer to warm plates. Spoon the fresh tomato sauce over, finish with grated Pecorino Sardo, and serve immediately — the pasta should be plump and intact, the sauce light and bright against the pale dough.
