Al Limone
Butter, lemon, and Parmigiano. From the Amalfi Coast, where the lemons are so fragrant they define the landscape.
Pasta al limone comes from Campania and the Amalfi Coast, where the sfusato amalfitano lemon grows in terraced gardens above the sea. The sauce is a simple emulsion of butter, lemon, and Parmigiano, built on the acid and aroma of the lemon, not on cream or egg. The original version uses only the lemon's zest and a squeeze of juice, relying on butter and pasta water to carry the flavour. Cream is a later addition, common outside Italy, and entirely unnecessary.
Only a few ingredients
Butter
Cold butter into a cold pan, then low heat. Let it melt slowly. The milk solids should stay pale, not brown.
Lemon
Zest first, grated directly into the melting butter. Then a squeeze of juice, not more than half a lemon per two people. The zest is the flavour; the juice is the edge.
Pasta Water
A generous splash. Off the heat. The water and butter emulsify into a creamy, opaque sauce.
Parmigiano Reggiano
Off heat. Grated fine. Stir until it melts into the sauce. It should tighten and thicken immediately.
Black Pepper
Freshly ground. Just before serving.
No cream. The emulsion is the technique.
Cream in pasta al limone is a sign that the cook does not trust the butter and water to do their work. They will. The combination of butter, pasta water, and Parmigiano produces a creamy emulsion that carries lemon flavour more cleanly than cream ever could. Cream muffles the lemon; the butter-and-water emulsion lets it through.
Spaghetti
The standard choice. The strands carry the light emulsion well.
Linguine
Flat surface picks up more of the butter-and-lemon coating.
