How to Actually Season with Salt

The most common cooking instruction is also the most misunderstood: season to taste. In most kitchens, this translates to adding salt at the end, after the food is cooked, until it no longer tastes flat. This produces food that tastes salty on the surface and bland inside. It is not the same as properly seasoned food.

Salt does several things, and they happen at different times. Understanding this changes how you use it.

What salt does

**It suppresses bitterness.** This is a physical fact. Salt at low concentrations directly suppresses bitter taste receptors. This is why a pinch of salt in coffee makes it taste smoother, why salted caramel works, and why salt added to cooking vegetables makes them taste less bitter before they taste salty.

**It enhances other flavours.** Salt increases the volatility of flavour compounds, which means more flavour molecules reach your nose. A properly seasoned dish tastes more intensely of itself.

**It draws out moisture.** Salt on the surface of food creates an osmotic gradient — moisture moves outward. For vegetables, this softens them and concentrates flavour. For meat before cooking, this initial moisture loss is followed (after 30–45 minutes) by reabsorption, which carries dissolved salt back into the muscle.

**It modifies texture.** In pasta dough, bread and cured fish, salt interacts with proteins to change structure. In pasta water, it seasons the pasta from the inside out as it absorbs water during cooking.

Seasoning at every stage

The rule is: add small amounts of salt at every stage of cooking, not a large amount at the end.

**Before cooking:** Salt meat at least 30 minutes before — ideally hours or overnight. The initial moisture drawn to the surface dissolves the salt, and then the brine is reabsorbed into the meat. Chicken skin salted several hours before has already begun to dry out, which helps it crisp. Steaks salted overnight form a dry brine.

**During cooking:** Salt vegetables as you add them to the pan. Salt the pasta water generously (it should taste like mild seawater, roughly 10g salt per litre). Salt onions early in a soffritto so they release their moisture and cook down properly.

**During development:** When a sauce reduces, its saltiness concentrates. Season lightly early, then adjust at the end after reducing.

**At the end:** A final adjustment for brightness — but only an adjustment, not the primary seasoning.

The pasta water question

Pasta water should be well-salted: around 10g of salt per litre of water. This is not about making the pasta salty — most of the salt stays in the water. It is about seasoning the inside of the pasta as it absorbs water during cooking. Unsalted pasta is bland all the way through; well-salted pasta is seasoned throughout its structure.

The common fear that salt "raises the boiling point" of water and slows cooking is technically true but practically irrelevant. The increase at any culinary quantity of salt is around 0.5°C. It makes no difference.

Different salts

Fine table salt and flaky sea salt (Maldon, Fleur de sel) contain the same sodium chloride but behave differently. Fine salt dissolves instantly and distributes evenly — useful for seasoning during cooking. Flaky salt dissolves slowly and provides textural contrast — best as a finishing salt on meat, fish or vegetables, or on chocolate. The flakes crush under the tooth and release a brief, intense burst.

The most important practical point about salt is simpler than the chemistry: taste as you cook, season in layers, and you will never need to reach for the salt shaker at the table.
