Tagliatelle al Tartufo Bianco di Acqualagna — Egg Pasta with White Truffle
Acqualagna, in the Metauro valley of the Pesaro-Urbino province, is one of Italy's two great white truffle centres (alongside Alba in Piedmont) — producing Tuber magnatum pico from October through January in the oak and poplar forests of the northern Marche Apennines. The definitive preparation is the simplest: freshly made egg tagliatelle tossed with good butter and a thread of the best available olive oil, finished with a generous shaving of Acqualagna white truffle at the table. No cheese, no garlic, no further seasoning — the truffle is the entire preparation. The pasta must be delicate enough not to compete; the butter must be of excellent quality; the truffle must be shaved at the last moment.

The Method
1
Mound the flour on a clean work surface and make a well. Break the eggs into the centre. Work the eggs into the flour with a fork, then with the hands, until a rough dough forms. Knead for 8–10 minutes until the dough is smooth, firm and elastic. Wrap and rest at room temperature for 30 minutes. The dough is ready when it springs back slowly under a pressed thumb.
2
Divide the dough into four pieces. Roll each through a pasta machine, progressively narrowing the setting, to setting 6 — a thin, semi-translucent sheet. Cut strips 5–6 mm wide. Lay the tagliatelle on a clean cloth and dry for 15 minutes. The pasta is ready when the surface feels dry to the touch but the strands remain pliable.
3
Bring a large pot of water to a rolling boil and salt it abundantly. Melt the butter over the lowest possible heat in a wide pan large enough to toss the pasta. Add the thread of mild olive oil. The butter must not colour or foam aggressively — it is ready when it is entirely liquid, pale, and faintly fragrant.
4
Cook the tagliatelle in the boiling water for 2–3 minutes. Drain, retaining a small ladleful of the pasta cooking water. Transfer the tagliatelle immediately to the butter pan. Toss gently over low heat, adding a splash of the retained pasta water to marry the butter into a light emulsion. This is the step on which the dish lives or dies: the pasta must reach the plate glossed in butter, perfectly seasoned by its own cooking water, with no pooling of fat and no dryness — the balance is achieved only in these few seconds of tossing, and must not be delayed. The tagliatelle are ready when every strand glistens and the pan shows no standing butter.
From the canon — Pasta cooking water contains dissolved starch (released from the pasta surface during boiling) at a concentration that increases with pasta-to-water ratio an… Pasta Water: Starch Concentration and Sauce Binding →

Plate immediately into four warm bowls. Bring the cleaned, dried truffle and a mandoline truffle slicer to the table. Shave the truffle generously over each portion at the moment of serving — not in the kitchen, not in advance. The truffle is ready when its fragrance fills the room within seconds of each slice falling onto the hot pasta.

Quality Hierarchy
01
Reserve — Acqualagna Tuber magnatum pico purchased directly at the fiera (October–November) or from a specialist; eggs stored with the truffle for 48 hours; French or Irish cultured butter at 84% fat or above; pasta rolled to setting 6 on the day.
02
Estate — Acqualagna or Alba white truffle from a named specialist importer; high-quality Italian or French unsalted butter; fresh eggs from a known producer; pasta made and cooked the same day.
03
Market — White truffle (any Tuber magnatum pico) sourced from a reliable Italian delicatessen in season; good supermarket unsalted butter; fresh commercially made egg tagliatelle (not dried).
04
House — The dish does not exist at the House rung: no real white truffle, no dish. Commercial truffle oil is explicitly excluded as a substitute.

Sensory Tests
◇Touch. The rested dough springs back slowly and evenly when pressed with a thumb — neither sticky nor cracking at the edges.
◇Touch. The cut tagliatelle on the cloth feel dry at the surface yet bend without snapping — 15 minutes of air-drying achieves this.
◇Sight. The melted butter in the pan is entirely liquid and pale gold; no browning at the edges, no separation.
◇Sight. Every strand of the tossed tagliatelle glistens with an even butter emulsion; no fat pools on the base of the pan or the plate.
◇Smell. Within seconds of the truffle being shaved at the table, its volatile aroma — earthy, garlicky, faintly honied — fills the immediate air around the plate.
◇Where it lives or dies. The tagliatelle must be tossed in the butter pan and plated in one continuous movement — any pause causes the butter to separate or the pasta to seize, and the truffle shaved over a cold or greasy plate is wasted.
