Salt Types: Kosher, Table, Sea, and Flaky Finishing Salt

Walk the salt aisle and you face a dozen boxes claiming different destinies. Here is the liberating truth: dissolved in food, all pure salt tastes essentially identical — the differences are crystal size, shape, additives, and price. What matters is matching the salt to the job: cooking salt you can pinch, measuring salt that behaves, and finishing salt with crunch. Three salts cover everything.

The only three salts you need

Everything else — pink Himalayan, smoked, black lava — is seasoning with a story, not a necessity. Buy them for fun, never from need; no dish requires them.

The conversion that prevents disasters

Because crystals differ in size, a tablespoon of one salt is not a tablespoon of another — this is the #1 salt mistake. Diamond Crystal kosher is fluffy (about half the salt per spoon as table salt); Morton kosher is denser; fine table salt packs tightest. The safe conversions:

• 1 tbsp Diamond Crystal kosher ≈ 2 tsp Morton kosher ≈ 1.5-2 tsp fine table salt.
• When a recipe just says "1 tablespoon salt" without specifying, it usually means Diamond Crystal — using table salt 1:1 doubles the salt.
• For brines and baking, weigh salt in grams — weight is identical across brands and eliminates the guessing entirely.

Kosher salt: the workhorse, with one catch

Kosher salt earned its status honestly: additive-free, dissolving cleanly, with flakes you can see and feel as you season — pinching gives far better control than shaking. The catch is the brand split: Diamond Crystal and Morton differ so much in density that recipes written for one overshoot or undershoot with the other. Pick one brand as your house salt and learn its strength; convert when borrowing recipes from the other camp.

When finishing salt earns its price

Flaky sea salt is the one luxury salt worth buying, because its job is texture, not just salinity — scattered over sliced tomatoes, chocolate chip cookies, grilled steak, or avocado toast, the crystals crunch and melt in bursts that fine salt cannot imitate. Use it only where it stays visible and dry; dissolved into soup, a $10 box performs exactly like the cheap one. Iodized vs non-iodized matters only in one place: ferments and pickles, where iodine can inhibit cultures and cloud brine — otherwise, cook with what you have.

How much salt, actually

As a starting point for savory cooking: about 1 teaspoon of Diamond Crystal kosher per pound of meat or vegetables, and 1 tablespoon per 2 quarts of pasta or blanching water — then taste and adjust. Professional food often carries around 1% salt by weight. The real skill is tasting at every stage; salt early enough to dissolve and meld, and finish by tasting, not by measuring.

The key takeaway: kosher for cooking, fine for baking, flaky for finishing. Mind the brand conversions, weigh salt for brines, and spend money only on the finishing flakes — their crunch is the one thing cheap salt can't fake.

Type is half the salt skill; technique is the rest — how to salt properly covers timing and tasting. And salt's biggest showcase is the brine: wet-brining science with the calculator.
