Culurgiones d'Ogliastra con Patate e Menta

Mound the semolina on the work surface, add the salt, and work in the lukewarm water gradually, kneading firmly for 8–10 minutes until the dough is smooth, firm, and distinctly elastic — unlike egg pasta, it will feel resistant under the hands, and that resistance is correct, since semolina needs prolonged working to develop the tight structure that will hold the spighetta seal under boiling water. Wrap and rest at room temperature for at least 30 minutes so the dough relaxes enough to roll without springing back stubbornly. The dough is ready when it springs back slowly but completely after a thumb-press.

Peel the boiled potatoes while still hot and pass them through a ricer or mash thoroughly — no lumps — then immediately work in the grated Pecorino Sardo, the minced garlic, the lard, and the chopped fresh mint, because the heat of the potato draws the fat from the lard and melts the cheese into a single cohesive mass that would stay grainy and separate if the potato were allowed to cool first. The filling is ready when it holds its shape when pressed but is still faintly warm and uniformly smooth, with the mint distributed evenly throughout. Do not allow it to cool completely before proceeding.

Roll the rested dough to a thickness of approximately 2–3 mm — thin enough to seal cleanly at the braid but substantial enough that it will not tear under the weight of the filling. Cut rounds of 8–9 cm diameter. Place a generous teaspoon of filling at the centre of each round, keeping a clear border of at least 1 cm all around so there is enough dough to grip and fold without the filling pushing out to the edge.

Fold the round over the filling to form a half-moon, then seal each culurgione with the spighetta — the wheat-ear braid — beginning at one end of the seam: pinch the edge firmly between thumb and forefinger, fold a small tab of the upper edge over itself and press with full, even pressure to seal, then repeat this overlapping fold deliberately along the entire seam toward the other end, because each fold must be completely set before the next begins or the accumulated tension will cause earlier folds to loosen. This is where the dish lives or dies: a hurried or insufficiently pressed fold will open in the pot, losing the filling entirely. The finished seal should resemble a braided wheat ear running the full length of the parcel.

Pass the ripe tomatoes and cook them briefly in a pan, stirring, until they lose their raw smell and thicken slightly, since a sauce that is still sharp and watery will thin further on the hot pasta and pool on the plate rather than coating it. Remove from heat and set aside. The sauce is ready when its colour deepens from bright to a muted brick-red and it no longer smells sharp and raw.

Bring a large pot of salted water to a gentle simmer — not a rolling boil — so the turbulence does not batter the braid open before the dough has had a chance to set around the seal. Lower the culurgiones in carefully, in batches if necessary to avoid crowding, and cook at a steady, gentle simmer for 6–8 minutes. The culurgiones are done when they float and the dough at the thickest point of the seal feels tender but not collapsing when pressed very lightly with a fingertip.

Lift the culurgiones from the water with a slotted spoon and transfer to warmed plates. Spoon the tomato sauce over, add a few leaves of fresh basil, and serve immediately. The pasta should glisten and the braid remain intact and clearly defined.
