What Cure #1 means
Cure #1 is a common name for a nitrite-containing curing blend. A frequently encountered formulation is 6.25% sodium nitrite with the balance primarily salt, but the exact product you own should be verified from its label.
Why 6.25% matters
The percentage is not a decorative specification. It determines how much curing blend is needed to deliver a target modeled sodium-nitrite concentration. If the product concentration changes, the calculated cure mass changes too. When you are ready to run your own numbers, the Cure #1 calculator applies this percentage to any batch size and nitrite target.
Cure #1 is not table salt
Table salt, kosher salt and pickling salt are sodium-chloride ingredients. Cure #1 is a different formulation that contains sodium nitrite. Pink Himalayan salt is also not a substitute for a nitrite curing blend.
When the recipe calls for Cure #1
Use the product and amount specified by a tested recipe or validated formulation. The calculator can expose the arithmetic, but it cannot decide whether a particular product or process is appropriate.
How to avoid mistakes
- Read the exact package label.
- Measure small cure quantities by mass rather than guessing by spoon.
- Keep curing ingredients clearly separated from ordinary salt.
- Check the calculation basis before interpreting the PPM result.
Read the label before doing the math
The label is the source of truth for the product concentration you actually own. A calculator cannot safely infer a cure concentration from color, brand name or a product nickname. Two products can both be described informally as a "pink cure" while having different ingredient compositions. Record the sodium nitrite percentage, and any nitrate percentage, exactly as printed on the package.
That matters because the same target PPM produces a different cure mass when the nitrite fraction changes. The relationship is direct: a more concentrated cure requires less product by mass to deliver the same modeled nitrite amount, while a less concentrated cure requires more. The calculator exposes this relationship instead of hiding it behind a fixed spoon measurement.
Worked calculation example
Suppose a formulation is modeled on a 1,000 g calculation basis and the selected cure contains 6.25% sodium nitrite. For a chosen target PPM, the calculator first converts the label percentage to a decimal fraction and then applies:
The result is a mass of curing blend, not a volume measure. This distinction is why a gram scale is preferable to a teaspoon or tablespoon for small cure quantities. The displayed number is an arithmetic result for the inputs you supplied; it is not, by itself, a validated process recommendation.
What can make a result unsuitable?
- The product label does not match the concentration entered into the calculator.
- The recipe uses a different calculation basis, such as meat plus water or a green-meat basis.
- The recipe is subject to a product-specific regulation, validated process, or manufacturer instruction that differs from the selected reference.
- The curing, cooking, sanitation, refrigeration or storage process is not controlled separately.
Cure #1 in context
Cure #1 is best treated as a named class of curing blend rather than a universal recipe number. Its purpose and the amount used depend on formulation, product specifications and the process being followed. Use the calculator to understand the math, then compare the output with the exact recipe or validated formulation you intend to follow.
Common names and brands for Cure #1
Shoppers meet this ingredient under many names, which is one of the most common sources of confusion. The following trade and generic names most often refer to a 6.25% sodium nitrite blend, but the package in your hand is always the final authority:
| Common name | Typical composition | Notes |
|---|---|---|
| Prague Powder #1 (Pink Curing Salt #1) | 6.25% sodium nitrite, ~93.75% salt | The most widely referenced U.S. brand name; dyed pink to discourage accidental use as table salt. |
| Insta Cure #1 (Instacure #1) | 6.25% sodium nitrite | Same formulation class, distributed under a different brand; verify the label percentage. |
| D.Q. Curing Salt #1 | 6.25% sodium nitrite | Another retail name for the same blend class. |
| Hoosier Hill Farm, Butcher & Packer and similar store brands | Usually 6.25% sodium nitrite | Retail packaging varies; always confirm the printed percentage. |
| Morton Tender Quick | 0.5% nitrite + 0.5% nitrate | Not a 6.25% product. Directions and dose differ — see our Tender Quick calculator. |
The last row is the trap worth repeating: many search results treat “pink salt,” “curing salt” and “Tender Quick” as one interchangeable thing. They are not. The calculator on our Cure #1 calculator page takes the label percentage as an input precisely because products differ.
Where Cure #1 is typically used
Cure #1 is intended for cured products that are cooked or otherwise processed within a relatively short window, where nitrite — not nitrate — does the curing work. Typical applications include:
| Product | Typical role of Cure #1 | Common formulation approach |
|---|---|---|
| Bacon (pork belly) | Primary curing ingredient | Dry-cured or pumped; U.S. references cap ingoing nitrite at 200 ppm dry and 120 ppm pumped/immersion — see our bacon calculator. |
| Ham (wet-cured) | Curing agent in brine or pump | Applied on a meat-plus-water or green-weight basis depending on the process. |
| Corned beef / pastrami | Brine or dry rub component | Often paired with a spice rub for pastrami after the brine stage. |
| Cured jerky | Pre-cook curing step | Marinade-based; see our jerky curing guide. |
| Cooked sausage (e.g., frankfurter-style, summer sausage) | Comminuted-product cure | The 156 ppm figure is the U.S. ingoing reference for comminuted sausage products. |
For long dry-cured products aged over weeks or months — salami, coppa, bresaola — recipes usually call for Cure #2 instead, because nitrite alone depletes early while nitrate acts as a slow reservoir. The Cure #1 vs Cure #2 guide walks through that decision.
How much Cure #1 to use per pound or kilogram
At the common 156 ppm ingoing target, a 6.25% product works out to 1.13 g per pound (2.5 g per kg) — the same 0.25%-of-meat-weight convention behind the classic manufacturer direction of “1 level teaspoon per 5 lb.” That equivalence is not a coincidence: 1 level teaspoon of Cure #1 weighs roughly 5.7 g, and 5.7 g × 6.25% = 356 mg of nitrite, which across 2.268 kg (5 lb) is about 157 ppm. Manufacturer spoon directions are built to land in this range.

When precision matters (and with cure it always should), weigh the blend on a gram scale; our weighing guide covers scales, taring and the teaspoon-versus-gram problem in detail.
Handling and storage of Cure #1
- Label the container immediately. Never store a nitrite blend in an unmarked bag or a salt cellar. Accidental confusion with cooking salt is the single most serious failure mode.
- Keep it dry, cool and dark. A sealed container in a pantry keeps the blend free-flowing for years; clumping is a moisture signal, not a safety failure, but caked product is harder to weigh accurately.
- Keep away from children and pets. Ingesting grams of pure sodium nitrite — not the diluted blend, the raw chemical — is dangerous to humans and animals. The pink dye exists to make accidental consumption less likely.
- Do not eat the blend by itself and do not taste it to “check” it.
- Check the date and clump state if the product has been open for years; when in doubt, replace it — curing salt is inexpensive relative to the meat it seasons.
Is nitrite in cured meat dangerous?
Nitrite has a genuine dual character: at controlled ingoing levels it is the working ingredient that suppresses Clostridium botulinum growth and gives cured meat its characteristic color and flavor, while at very high doses it is toxic to humans. That is exactly why regulations such as 9 CFR 424.21 set specific ingoing maximums per product category rather than leaving the amount to guesswork, and why a formulation calculator — used honestly, with your real label percentage — is a safer workflow than spooning cure “until it looks right.” Residual nitrite in the finished product is typically far lower than the ingoing amount because nitrite is consumed and converted during curing and cooking.
Frequently asked questions about Cure #1
Is Cure #1 the same as pink Himalayan salt?
No — and confusing the two is dangerous as well as frustrating. Pink Himalayan salt is ordinary sodium chloride with trace minerals that give it a pink color and zero nitrite; it cannot cure meat. Pink curing salt (Prague Powder #1 and similar) is a blend containing 6.25% sodium nitrite that is dyed pink on purpose so the two products never look alike. If a recipe calls for curing salt, pink Himalayan salt is not a substitute in any amount.
Can I use Cure #1 for jerky?
Yes — Cure #1 is the standard curing ingredient in most U.S. jerky recipes, where it is mixed into the marinade before drying. The common target is the same 156 ppm ingoing level used for comminuted products, which works out to about 1.13 g of a 6.25% blend per pound of sliced meat. Jerky also needs the validated drying step (heat treatment to 160 °F / 71 °C for whole-muscle strips in USDA guidance) — curing handles the formulation, not the lethality step. Our jerky page covers the math.
What happens if I add too much Cure #1?
The formulation stops matching the reference range the recipe was built on, and the product can taste metallic or “cured-ham sharp” at moderate overdose; at much higher levels nitrite itself becomes a poisoning risk. There is no home remedy that removes excess nitrite from a batch — if the math says you overdosed, the safe answer is to recalculate the batch from scratch with corrected weights rather than trying to dilute or rinse it. This is why weighing to 0.1 g and inspecting the calculator’s math breakdown before mixing matters.
Can I swap Cure #1 for Morton Tender Quick?
Not one-for-one. Tender Quick carries roughly 0.5% nitrite (plus 0.5% nitrate) — about one-twelfth the nitrite strength of a 6.25% blend — so a straight swap leaves the batch radically under-cured. If a recipe calls for Cure #1, use a 6.25% product; if you only have Tender Quick, follow Tender Quick’s own directions or run the numbers in our Tender Quick calculator. The Tender Quick vs Cure #1 comparison explains the trade-offs.
Does cooking destroy the nitrite I calculated for?
Cooking reduces residual nitrite substantially — much of the ingoing nitrite is converted to nitric oxide and other compounds during curing and cooking, which is part of how the color and flavor form. That is normal chemistry, not a calculation error: the ingoing PPM figure you compute is a formulation-control number used by recipes and regulations, not a prediction of the final nitrite content on the plate.
