What Italians Know About Pasta That We've Forgotten

The Cardinal Rule

Pasta water should taste like the sea. Not brackish — but genuinely, assertively salty. This is the single most important thing most home cooks get wrong. Pasta cooked in under-salted water is starchy and flat, entirely dependent on whatever sauce you dress it with. Pasta cooked in properly salted water has seasoning built into every millimetre of its structure.

Use at least 10 grams of salt per litre of water. Almost none of it ends up in the pasta.

Al Dente Is a Moment, Not a Texture

"Al dente" translates as "to the tooth." It describes a specific moment: when the strand still has a faint resistance at its very centre. And it should not quite be done — because it's going to finish cooking in the sauce.

This is the part the packet never tells you: the pasta goes into the pan with the sauce two minutes before you'd want to eat it. The residual heat, the starchy pasta water, and the gentle toss in the pan complete the cooking. The pasta absorbs the sauce. The sauce clings to the pasta. They become one thing.

Pasta Water: Don't Throw It Away

The water left behind after boiling is one of the most useful liquids in your kitchen. It's starchy, salty, and slightly thickened — the ideal emulsifier for turning separate pools of fat and liquid into a unified, glossy sauce.

A classic cacio e pepe — made with nothing but pasta, pecorino, black pepper, and pasta water — is essentially impossible to make without it. Reserve at least a full mug before you drain.

Shape Is Not Arbitrary

The relationship between pasta shape and sauce is functional, not decorative. Tubes trap chunky, meaty sauces in their hollow centres. Long strands suit smooth, oil-based sauces that coat each strand. Wide ribbons are paired with robust ragù. When Italians insist on a specific pairing, it's centuries of working out what actually tastes better.
