Chapter 3 · Cooking Pasta Properly: Salting, Al Dente & Pasta Water

Boiling pasta looks like the simplest step in Italian cooking, and it's also the step most home cooks get subtly wrong — under-salted water, pasta cooked past the point it should be, and the starchy water that later chapters actually need poured straight down the drain. None of it takes extra skill, just three specific habits.

Salting the Water: "Like the Sea"

Pasta is cooked in a large pot of water, and that water is one of the only real chances you get to season the pasta itself from the inside — a sauce added afterward only seasons the surface. The common Italian guidance is to salt the water until it tastes like the sea — genuinely, noticeably salty on its own, far saltier than you'd want a soup or a broth to taste.

Use a large pot with plenty of water Pasta needs room to move freely as it cooks, which is also why Chapter 1 flagged a large pot as essential equipment — a crowded pot cooks unevenly and releases enough starch to turn the water gluey.
Bring the water to a full boil first Salt dissolves faster and more evenly in already-boiling water, and starting with fully boiling water also means the pasta starts cooking immediately rather than gradually as the pot slowly heats up.
Salt generously, then taste it A rough starting point is about 1–2 tablespoons of coarse salt per 4–6 litres of water — but the real test is tasting a spoonful of the water itself. It should taste clearly, distinctly salty, not just faintly seasoned.

Only a fraction of that salt ends up on your plate Salting the water this generously can feel alarming the first time, but the pasta only absorbs a small portion of the salt in the water as it cooks — most of it goes down the drain with the water itself. This is exactly why the water needs to taste far saltier than you'd want the finished dish to taste.

Testing for Al Dente

Al dente literally means "to the tooth" — pasta cooked until it's tender but still has a slight, genuine resistance right at the centre when you bite into it, not a soft, fully yielding texture all the way through.

Pasta type	Typical cook time	Testing habit
Fresh egg pasta (Ch.2)	Roughly 2–4 minutes	Cooks far faster than dried — start tasting almost immediately after it returns to a boil
Dried pasta	Roughly 8–12 minutes, varies by shape	Use the package time as a rough guide only, and start tasting 1–2 minutes before it's supposedly done

The package time on a box of dried pasta is a manufacturer's estimate, not a guarantee — the only real way to know your pasta is done is to fish out a piece and taste it. You're looking for a texture that's tender throughout but still offers a small, clean bite of resistance right in the centre, not a chalky, undercooked core and not a mushy, fully-soft one either.

Reserving the Pasta Water

Before you drain the pot, scoop out at least a cup of the starchy cooking water and set it aside. That cloudy, salted water is loaded with starch released from the pasta as it cooked, and it becomes a real working ingredient once you start building sauces from Chapter 4 onward — added a splash at a time, it helps a sauce emulsify and cling to the pasta rather than sitting as a separate layer of oil and liquid.

This matters most in Chapter 5 Aglio e olio and cacio e pepe (Chapter 5) rely on pasta water almost entirely to bring their sauce together — there's no cream, no roux, nothing else doing the emulsifying work. Getting into the reserving habit now, before those recipes actually depend on it, means you won't be caught out later with an empty pot and nothing to add.

Draining: Never Rinse

Drain the pasta in the colander from Chapter 1's equipment list — but don't rinse it under running water afterward. Rinsing washes away the same surface starch the pasta water above relies on, and that starch is exactly what lets a sauce cling to the pasta rather than sliding off it. Rinsed pasta ends up slick and under-seasoned, with the sauce pooling at the bottom of the bowl instead of coating each piece.

The one real exception: cold pasta salad If you're making a cold pasta salad and genuinely need to stop the cooking quickly and cool the pasta down, a rinse under cold water is the one legitimate exception to this rule — you're not trying to coat it with a hot sauce afterward, so the lost starch doesn't cost you anything.

Kitchen Practice

Kitchen Practice 1

Cook a batch of dried pasta, salting the water until it genuinely tastes like the sea. Taste the water before adding pasta, then taste the pasta itself once cooked, and note how the two compare.

→ Solution

Kitchen Practice 2

Cook the fresh pasta dough you made in Chapter 2, starting to test it for doneness almost immediately once the water returns to a boil. Compare its actual cook time against a batch of dried pasta.

→ Solution

Kitchen Practice 3

Cook two small batches of pasta side by side — rinse one under cold water after draining, and leave the other unrinsed. Toss each with a small amount of olive oil and compare how well the oil coats each batch.

Quick Reference — Cooking Pasta Properly

Salt the water generously, until it tastes like the sea — added after the water is already boiling
Al dente means tender with a slight bite left at the centre — test by tasting, not by the clock
Fresh pasta cooks in roughly 2–4 minutes; dried pasta in roughly 8–12, varying by shape
Reserve at least a cup of starchy pasta water before draining — essential for Chapter 5's sauces
Never rinse cooked pasta (except for a cold pasta salad) — rinsing washes away the starch a sauce needs to cling
