Salting: When to Do It, How Much, and Why a Teaspoon of Salt Is Not a Teaspoon
Ask a cook who trained in a restaurant what separates their food from most home cooking and the honest answer is usually salt: more of it, earlier, and with more confidence. Home cooks undersalt because the box says so, because the doctor said so, and because the moment to add it passed while they were reading the next step. Then there is a stranger problem that nobody warns them about. The word "salt" covers grains so different in size that a teaspoon of one weighs nearly twice as much as a teaspoon of another, so a recipe written with one salt and cooked with another is wrong before the stove is on. This piece is the physics of that, a table that fixes it, the timing rules for the main things you salt, and the rescue for when you have gone too far. Our salt harvesting piece explains where the grains come from; our finishing salt guide covers the flake on top. This is the salt in the pot.
Why a teaspoon is not a teaspoon
Salt is sodium chloride whatever the box says, and a gram of it seasons the same amount of food regardless of shape. What changes is how much air is in the spoon. Fine table salt packs densely: a level teaspoon is about 6 grams. Morton kosher salt is a flattened flake and packs less densely: about 4.8 grams. Diamond Crystal kosher salt is a hollow pyramid and packs least of all: about 2.8 grams. A recipe developed with Diamond Crystal and cooked with table salt delivers roughly twice the sodium the author intended, which is why so many "a teaspoon of salt" recipes taste either flat or fierce depending on whose kitchen they are cooked in. American recipe writers know this and most now name the salt. Weight is the only measure that is the same for everyone.
| Salt | Grams per level teaspoon | Teaspoons for 10 g | Relative to table salt |
|---|---|---|---|
| Fine table salt | about 6.0 | 1 2/3 | 1.0 |
| Fine sea salt | about 5.5 to 6.0 | 1 3/4 | 0.95 |
| Morton kosher | about 4.8 | 2 | 0.8 |
| Diamond Crystal kosher | about 2.8 | 3 1/2 | 0.5 |
| Flaky sea salt | about 2.5 to 3.5 | 3 to 4 | 0.5 |
The practical rule: when a recipe names a salt, use that one or convert by the table. When it names none, assume table salt if it is old or European, Diamond Crystal if it comes from a modern American test kitchen, and taste. A ten-dollar digital scale makes the whole problem disappear.
How much: the percentages
Cooks who season by weight use a few percentages and rarely miss. Pasta and blanching water: one percent, 10 grams per liter, as our pasta method lays out. A pot of beans or a soup: around 0.8 to 1 percent of the total weight of water and ingredients, added in stages. Meat, seasoned ahead: about one percent of the meat's weight, which is 10 grams per kilo or a scant teaspoon of table salt per pound. A wet brine for poultry or pork: five to six percent of the water's weight. Bread dough: two percent of the flour's weight. These are targets to taste toward, not laws; a salty anchovy or a Parmigiano rind in the pot counts toward the total, which is why recipes with cured ingredients say "salt to taste" near the end.
When: the timing rules
Water, first. Salt boiling water for pasta, potatoes, beans and vegetables at the start, so what cooks in it is seasoned through. Salting the water does not make beans tough; that is an old rule the evidence does not support, and salted beans cook with better skins and taste of themselves.
Meat, early. Salt a steak, a chicken or a roast at least forty minutes ahead and ideally the night before, uncovered in the refrigerator. In the first minutes salt draws moisture to the surface, which is why a steak salted five minutes before the pan sears badly; given time, that brine is reabsorbed and seasons the meat inside while drying the surface for a better crust. Between five and forty minutes is the worst window. Either right before the heat or well ahead.
Vegetables, it depends. Salt sliced eggplant, cucumber or cabbage ahead to draw water out, which is the point. Salt mushrooms after they brown, since salt pulls water into the pan and stalls the browning. Salt a green salad at the last second; dressed leaves wilt.
Sauces and stews, in stages. A little at the start, a little when the liquid goes in, and the final adjustment at the end when the volume is settled. A sauce that reduces concentrates its salt, so a stew seasoned "correctly" at the beginning is oversalted by the finish. Season lightly early, decisively late.
Eggs, before. Salting beaten eggs before they cook gives a more tender scramble, the opposite of the old warning.
The plate, last. Flaky salt on the finished dish is a texture as much as a seasoning; it is the crunch and the burst, and it is the one salt that goes on rather than in.
Salt is not only salty
Salt suppresses bitterness, which is why a pinch improves grapefruit, coffee and dark chocolate; it heightens sweetness, which is the whole argument for salted caramel in our caramel guide; and it makes aromas more perceptible, so an undersalted tomato sauce tastes less of tomato, not just less of salt. When a dish tastes flat, the first question is salt. When a dish tastes salty, the answer is usually not less salt but more of everything else: a squeeze of acid, a spoon of fat, a handful of the main ingredient. Our guide to fixing a dish from the shelf is built on that principle.
When you have gone too far
The potato does not work. A raw potato simmered in an oversalted soup absorbs a little salted liquid and a little salt, in the same proportion the soup already has; it does not pull salt out selectively. What works is dilution and balance: add unsalted liquid, more of the unsalted ingredients, a splash of acid, a spoon of something sweet or fatty. For a dry dish, serve it with something bland alongside, rice, bread, potatoes, and let the plate do the diluting. For a brined or salted piece of meat that went too long, a soak in fresh water for thirty minutes helps. The best rescue is not needing one: salt in stages and taste.
The salts on the shelf, by job
A fine salt for water, dough and seasoning by the spoon, where it dissolves fast and measures predictably. A coarse gray sea salt for pots, roasts and pasta water, where it dissolves slowly and brings a little mineral flavor from the marsh, as the harvesting piece describes. A flake for the plate. Kosher salt is the American cook's default for a reason: its coarse grains are easy to pinch and hard to overdose, and if it is the salt your recipes name, use it. Whichever you choose, use one salt for the pot consistently, learn what a pinch of it does, and salt with your fingers rather than a spoon, which is faster, more even and how every professional kitchen does it. The salts are at 263 Josephine Street in Cherry Creek, Denver, and ship nationwide from theambrosianpantry.com. Buy a scale with them; it is the cheapest thing that will make you a better cook.
