Dry Brining: How Much Salt, How Long, and Why Your Salt Brand Changes Everything

By James Nicholas · Researched from manufacturer nutrition panels, USDA FSIS, land-grant Extension publications and peer-reviewed meat science

The parts that matter

• Volume measurements are the whole problem. Reaching for Morton where a recipe meant Diamond Crystal over-salts by 71%. Reaching for table salt over-salts by 114% — you have more than doubled the dose.
• You can derive any salt’s density from its own nutrition panel. Divide the sodium milligrams by 0.39334. We validated the method against three Morton panels and it matched all three exactly.
• Two of the most trusted names in American cooking publish Morton substitutions that deliver 26 to 29% more salt by weight than the Diamond Crystal amounts they replace. America’s Test Kitchen’s Morton instruction delivers 25.7% more salt by weight than the recipe it tested. Serious Eats’ is 28.6% over. Arithmetic below.
• USDA and the internet flatly disagree on method. FSIS says sealed food-grade bag, up to 2 days. Every consumer page we checked says uncovered on a rack for up to 3 days.
• Check the label before you salt. The 3% cap on added solution no longer exists — the regulation behind it is marked [Reserved]. Butterball’s fresh whole turkey declares 4%, its frozen bird 8%.

What does dry brining actually do to meat?

Salt on a wet surface dissolves. The resulting concentrated brine draws water out of the muscle by osmosis, then — as the salt concentration inside and outside equalizes — that seasoned liquid is drawn back in. What changes along the way is the muscle’s ability to hold onto water when heat hits it.

The mechanism is well described in the peer-reviewed literature. Graiver and colleagues, studying salt diffusion in pork longissimus dorsi at 4 °C, attribute the effect to “the lateral expansion of myofibrils, which is coupled to protein solubilization” and to “enhanced electrostatic repulsion between myofibril filaments causing the filament lattices to expand for water entrapment.” In plain terms: salt makes the protein scaffolding swell and hold water.

USDA’s own poultry page quotes Dr. Alan Sams of Texas A&M to the same effect: “It dissolves protein in muscle, and the salt and protein reduce moisture loss during cooking.”

How much salt should you use, by weight?

Here is the number the entire category has been dancing around. Salt should be dosed as a percentage of the meat’s weight, because that is the only unit that survives a change of salt brand, a change of bird size, or a change of continent. It is the unit meat science already uses. It is used by almost no cookbook.

These targets are our synthesis of the published range shown further down, presented as an editorial convention rather than a discovered fact. No federal agency or Extension service publishes a percentage-of-weight dry-brine standard.

Why does the salt brand change everything?

“One teaspoon of kosher salt per pound” is not an instruction. It is a range. Kosher salt crystals differ so much in shape and density between brands that a teaspoon of one weighs a little over half a teaspoon of another.

What a teaspoon of each salt actually weighs

The method: read any salt’s density off its own label

Diamond Crystal publishes no gram weight on its box or its product page. It does publish sodium: 280 mg per ¼ teaspoon. Sodium is 39.334% of sodium chloride by mass, so:

280 ÷ 0.39334 = 711.7 mg of salt per ¼ tsp = 2.85 g per teaspoon.

We validated that method against the three Morton products that print both numbers, and it reproduced each printed weight exactly: 480 mg → 1.220 g against a printed 1.2 g; 590 mg → 1.500 g against a printed 1.5 g; 560 mg → 1.424 g against a printed 1.4 g. Three for three. You can now derive the density of any salt in any store — house brands included — from the panel on the back.

What happens when you grab the wrong box

Read each row as: “I used this salt where the recipe meant that one, at the same spoon volume.”

A 71% overdose is the difference between a seasoned bird and one nobody finishes. This is the single most common way a dry brine fails, and it has nothing to do with technique.

What do the published turkey ratios work out to?

Every widely-cited dry-brine ratio, restated as a percentage of a 13 lb (5,897 g) bird, in both salt brands:

The full published span is 0.31% to 1.47% — a 4.7× spread. And note the top row: a single federal recommendation ranges from 0.37% to 0.63% depending on which box is in your cupboard. USDA specifies “kosher salt” without naming a brand, and ships a 71% ambiguity along with it.

How long should you dry brine?

Long enough for the salt to travel. Salt moves through muscle by diffusion, and diffusion is slow, predictable, and indifferent to your dinner plans.

How far the salt actually gets

Using the effective diffusion coefficients Graiver and colleagues measured in pork at 4 °C, and the standard first-order penetration estimate, here is roughly how deep the salt front reaches:

Our calculation, from published coefficients, using a one-dimensional model. Real meat is not a semi-infinite slab and a dry brine’s surface film is far more concentrated than a soaking solution, so treat these as an order-of-magnitude bracket — roughly 3–9 mm at 24 hours, 5–16 mm at 72 hours.

That single table explains most of the confusion in this category. A 1-inch steak is meaningfully seasoned in a few hours. A turkey breast is never seasoned to the bone, not in 72 hours, not ever. Dry brining is a surface-and-near-surface technique, and the reason it works on a bird is that the outer centimeter is where the skin, the crust and most of the eating experience live.

Two independent cross-checks: the traditional country-ham rule of about an inch per week, attributed to Ziegler and Miller’s 1938 Pennsylvania Agricultural Experiment Station bulletin, runs roughly three times faster than pure diffusion predicts — real curing is not pure diffusion. And University of Kentucky work found penetration is muscle-specific: over 60 days at 4 °C the semimembranosus hit USDA’s 4% salt minimum throughout by day 30, the semitendinosus by day 60, and the biceps femoris only at its outer surface.

Published timings, and where they disagree

Note the steak row. Two of the most authoritative kitchens in America publish recommendations that differ by a factor of roughly forty — one hour on the counter versus two days in the fridge — and neither acknowledges the other exists.

Is the 40-minute steak rule real?

You will read everywhere that you should salt a steak either immediately before cooking or at least 40 minutes ahead, but never in between, because the window in the middle leaves the surface wet and kills the crust.

The rule traces to exactly one source: J. Kenji López-Alt, writing at Serious Eats in March 2011. His method, in his own description, was six thick-cut bone-in ribeyes salted at ten-minute intervals and seared, with the steaks that were salted immediately or rested at least 40 minutes turning out best.

That is n = 6, one trial, unblinded, judged by eye and palate by a single cook, and in fifteen years nobody has replicated it. The mechanism he proposes — surface water beading out and then being reabsorbed — is physically plausible and broadly consistent with the diffusion data above. But Serious Eats’ own more recent restatement has already widened the danger zone to “roughly 5 to 45 minutes,” and a number that drifts within a single publication is a number nothing is anchoring.

Our position: it is a reasonable working heuristic with a known author, a known date and a known sample size. Treat it as that, not as physics.

Is it safe to leave salted poultry uncovered in the fridge?

We are not going to pretend the conflict resolves cleanly, because it does not. Cooks go uncovered for a real reason: a dry refrigerator dehydrates the skin, and dehydrated skin is the entire point of dry-brining a bird. Covering it in a sealed bag gives up most of that benefit.

What we can tell you plainly:

• USDA’s published protocol is sealed bag, 2 days maximum. That is the conservative, agency-backed option and it is what we would recommend to anyone cooking for immunocompromised, elderly, pregnant or very young guests.
• The FDA Food Code 2022, section 3-302.11(A)(4), requires food in regulated kitchens to be stored “in packages, covered containers, or wrappings,” and its exemption list — which does cover primal cuts of raw meat on sanitized racks — does not exempt whole raw poultry. Home kitchens are not regulated by the Food Code, so this is an analogy rather than a rule, but it is the closest regulatory signal that exists.
• If you go uncovered anyway, keep the refrigerator at 40 °F or below, put the bird on the bottom shelf on a rimmed tray so nothing can drip onto ready-to-eat food, and stay inside 48 hours rather than stretching to 72.
• Cook poultry to 165 °F, checked in the innermost thigh, the innermost wing and the thickest part of the breast — the three points FSIS actually specifies, which we cover in detail in our guide to how to use a meat thermometer.

One more finding worth stating: Clemson is the only Cooperative Extension service we located that covers dry brining at all, and it gives no per-pound ratio. Illinois and Wisconsin Extension cover wet brining only. The .edu literature on this technique is essentially absent, which is a large part of why the advice online has never been checked against anything.

Is your turkey already brined? How to read the label

Dry-brining a bird that arrived pre-salted is the fastest way to ruin one. This is also the section where the guidance online — including USDA’s own consumer pages — is out of date.

The 3% cap no longer exists. FSIS consumer pages still say bone-in poultry may carry up to 3% added solution and boneless up to 8%. The regulation behind that, 9 CFR 381.169, now reads “[Reserved]” in the live Code of Federal Regulations. It was rescinded by the 2014 final rule on Descriptive Designation for Raw Meat and Poultry Products Containing Added Solutions (Docket FSIS-2010-0012), effective January 1, 2016. Caps were replaced by mandatory disclosure. There is no ceiling now — there is a number printed on the front of the package.

And the market has moved past the old cap: Butterball’s fresh whole turkey declares “up to 4% of a solution,” and its frozen whole turkey declares “up to 8%.”

Put items 1 and 4 together and a shopper can face a bird carrying up to about 12% added water from processing plus another 4–8% salt solution — two independent percentages, in two different places on the package, under two different regulations, before a single grain of your salt goes on.

If the label declares any added solution, skip the dry brine or cut it to a third and season for flavor only.

Dry brine or wet brine?

Here is a claim you will see everywhere that the evidence does not support: dry brining produces juicier meat than wet brining.

The most-cited experiment behind the entire dry-brine movement — López-Alt’s November 2012 Serious Eats test, 24 chicken breasts across four batches — found the opposite on moisture. He reports that brining cuts total moisture loss by 30–40%, and that the salted breast, while much moister than an unsalted one, was “a couple of percentage points drier than the brined breast.” His preference for dry brining is explicitly about flavor, not yield: the water a wet brine adds is, in his words, plain tap water.

No peer-reviewed head-to-head study of dry versus wet brining exists. We looked. The honest summary:

For the fuller comparison of the two techniques and when each earns its keep, see brine vs marinade. If you want maximum weight on the scale, wet brine. If you want the bird to taste more like turkey and the skin to shatter, dry brine. We would not tell you dry brining wins on juiciness, because the only real measurement says it does not.

How to dry brine, step by step

Dry brining is the first step in our smoked turkey guide and our crispy-skin whole chicken guide, and it is what puts the crust on a reverse-seared steak.

1. Read the label first. Any declared solution percentage means skip or drastically reduce the salt.
2. Weigh the meat in grams, or convert: pounds × 453.6.
3. Multiply by your target percentage from the table above. A 5,897 g (13 lb) turkey at 0.65% needs 38 g of salt.
4. Weigh the salt. If you have no scale, divide the grams by 2.8 for Diamond Crystal, 4.8 for Morton kosher, or 6.0 for table salt to get teaspoons. Our 38 g example is 13½ tsp of Diamond Crystal, 8 tsp of Morton kosher, or 6¼ tsp of table salt — three very different-looking piles doing exactly the same job.
5. Apply it everywhere — surface, cavity, and under the skin over the breast and thighs where you can loosen it without tearing.
6. Rest it cold. USDA: sealed bag, up to 2 days, massaged every 8–12 hours. Uncovered on a rack gives better skin; keep it under 48 hours and on the bottom shelf.
7. Pat dry and cook. Do not rinse a correctly-dosed dry brine — you would be washing off seasoning you measured. Poultry to 165 °F.
8. Salt the food at the table lightly, if at all. It has been seasoned from the inside.

Common dry-brining mistakes

• Measuring by volume without naming the brand. The 71% error. Everything else is a rounding difference by comparison.
• Dry-brining an enhanced bird. Check the front panel.
• Adding sugar-heavy rubs before a long rest. Fine for flavor, but sugar on a hot direct fire caramelizes at 338 °F and carbonizes shortly after. Add sweet rubs late — see our smoking times and temperatures chart for where each cut actually sits.
• Dry-brining ground meat. Salt dissolves myofibrillar proteins into a gel; the texture goes springy and sausage-like.
• Going to 72 hours because a blog said so. USDA says 2 days. The additional depth between 48 and 72 hours is roughly a millimeter or two.
• Salting fish like meat. Past about 90 minutes you are curing, not seasoning.

Where dry brining fits with everything else

Salt is the only seasoning ingredient that reliably travels into muscle. Everything else — herbs, spices, sugar, oil, acid — works on the surface, which is why marinating times follow completely different rules. Once the bird or the steak is seasoned, the next two variables are fire management and internal temperature: our guide to setting up a charcoal grill covers the first, and the smoking times and temperatures chart covers the second. For the wider story of how salt, smoke and fire became American barbecue, see what barbecue actually is.

Across the Brand Avalanche network, our colleagues at Current Homesteading cover the other end of the salt-and-preservation spectrum in their home canning times and pressures chart.

What we refused to publish

• “Don’t exceed 72 hours or the intramuscular fat dries out.” Stated by one manufacturer with no source and no mechanism. We found nothing supporting it.
• A percentage figure for “less moisture loss from dry brining.” The only measured moisture numbers we located are for wet brining. Laundering them into dry-brine claims is how bad numbers get born.
• Any figure for what share of American turkeys are sold pre-brined. No USDA, AMS or National Turkey Federation source publishes it.
• “Look for ‘enhanced’ on the label.” Legally impossible since 2016.
• The 3% added-solution cap. The regulation is [Reserved]; Butterball’s own fresh bird exceeds it.

Frequently Asked Questions

How much salt should you use for dry brining?

Roughly 0.5–0.75% of the meat’s weight in salt, and weigh it rather than measuring by volume — brands differ enormously. One teaspoon is 2.8 g of Diamond Crystal kosher salt, 4.8 g of Morton kosher salt, and 6.0 g of table salt.

Does the brand of salt actually matter for dry brining?

Yes, substantially. Reaching for Morton where a recipe meant Diamond Crystal over-salts by 71%; reaching for table salt over-salts by 114%, more than doubling the intended dose. Two widely trusted recipe sources publish Morton substitutions that deliver 26–29% more salt by weight than the Diamond Crystal amounts they were meant to replace.

How long can you dry brine meat in the refrigerator?

USDA FSIS caps refrigerated dry brining at 2 days in a sealed food-grade bag. Most consumer recipe sources instead recommend leaving the meat uncovered on a rack for up to 3 days — a genuine disagreement between the federal method and common recipe advice, not a typo.

Do I need to worry about pre-brined or “enhanced” turkey before dry brining it?

Yes — check the label first. Added-solution percentages vary by product: Butterball’s fresh whole turkey declares 4% added solution, its frozen bird 8%. A pre-brined bird needs less or no additional salt.

How long should you dry brine a steak?

Serious Eats puts the ideal at 12 to 48 hours uncovered on a rack in the refrigerator, with 45 minutes as the minimum. America’s Test Kitchen salts a steak 1 hour ahead at room temperature, at ¾ teaspoon per 8 ounces.

How long should you dry brine a turkey?

USDA FSIS allows up to 2 days in a sealed bag in the refrigerator, massaging the bird every 8 to 12 hours. America’s Test Kitchen and Clemson HGIC both use 24 to 48 hours, so a turkey salted one to two days ahead fits every source in the timing table above.
