Butter, sage, parmigiano. The classic dressing for filled pasta — tortellini, ravioli, agnolotti. The butter must brown. The sage must crisp. The parmigiano must melt into the sauce, not sit on top.

INGREDIENTS

What you actually need.

Serves

FRESH TORTELLINI OR RAVIOLI 500 g
UNSALTED BUTTER 100 g
FRESH SAGE 12 leaves
PARMIGIANO REGGIANO — finely grated 60 g
BLACK PEPPER — freshly ground freshly ground

NOTA BENE

This sauce exists for filled pasta. The richness of the butter matches the richness of the filling — with unfilled pasta there is nothing to balance it against.

METHOD

5 steps, and one will define the dish.

Cook the pasta.

In salted water until just tender. Reserve pasta water.

Brown the butter.

Medium heat, watch constantly — foam, then golden, then nutty hazelnut. 3–4 minutes.

Crisp the sage.

Into the browned butter, 30–40 seconds. Remove from heat.

Add pasta and cheese.

Off the heat, splash of pasta water, toss gently.

Fold in the parmigiano.

In two additions. Serve immediately.

WHY IT WORKS — THE SCIENCE

Brown butter is not burned butter.

Burro e salvia is not a sauce in the way that amatriciana or pesto is a sauce. It is a dressing — assembled in the time it takes to boil pasta, using two ingredients and a technique. It is also, done correctly, one of the most satisfying things you can put on filled pasta. The key word is correctly.

The butter must brown. This is not aesthetics — it is chemistry. As butter heats past the point at which the water evaporates, the milk solids begin to caramelise, producing hundreds of new aromatic compounds that raw or melted butter does not contain. The nutty, complex flavour of browned butter is completely absent from pale melted butter. They are not the same sauce.

Brown butter versus burned butter

The window between brown butter and burned butter is approximately 20 seconds and requires your full attention. Brown butter smells nutty and toasted. Burned butter smells acrid and tastes bitter. The colour difference is subtle — pale amber versus dark brown. Do not attempt this while doing anything else.

“The Italians have been browning butter for a very long time without calling it anything special. The French gave it a name — beurre noisette — and wrote papers about it. The Italians just kept cooking.”— VALENTINA HARRIS, ITALIAN FOOD WRITER

Why this sauce belongs to filled pasta

Burro e salvia was designed for pasta with a rich filling — pork and mortadella tortellini, ricotta and spinach ravioli, cheese and truffle agnolotti. The butter is the background against which the filling speaks. On unfilled pasta there is no filling — the butter simply dominates and the dish becomes rich and one-dimensional. Use this sauce for what it was made for.
