Can You Substitute Tender Quick for Cure #1?
No — not by swapping one for the other in a recipe.
The clean way to think about it: Cure #1 is a cure you add salt to. Tender Quick is the salt. Cure #1, at 0.25% of the meat weight, puts almost no salt in your meat, so the recipe salts separately. Tender Quick at Morton's own rate puts about 3.1% salt in. Swap them by weight and you either wreck the salt or under-cure the batch.
This is one of the most common questions in home curing, and most answers stop at "they're different." They are, but the useful part is how — because once you see what each product actually puts into the meat, it's obvious why a swap doesn't work.
What each one actually delivers, per pound of meat
| Product | Dose | Ingoing nitrite | Salt it adds* |
|---|---|---|---|
| Cure #1 (Prague Powder #1) | 1.13 g | ~156 ppm | ~0.23% |
| Tender Quick — whole cuts | 1 Tbsp (14.2 g) | ~156 ppm + nitrate | ~3.1% salt + sugar |
| Tender Quick — ground meat | ½ Tbsp (7.1 g) | ~78 ppm + nitrate | ~1.6% salt + sugar |
| Peklosol (Polish cure) | 11.8 g | ~156 ppm | ~2.5% |
* Tender Quick's base is salt and sugar, so its figure is the combined weight of both, not salt alone.
Read the last column. Cure #1 contributes 0.23% salt; Tender Quick contributes thirteen times that. A sausage recipe that already carries its own salt and then gets Tender Quick dropped in where the Cure #1 went comes out inedibly salty. Go the other way, using Cure #1 where a recipe expected Tender Quick, and you lose most of the salt the recipe was counting on.
Three reasons they aren't interchangeable
1. Tender Quick contains nitrate. Cure #1 does not. Nitrate breaks down slowly into nitrite over a long cure. That's useful in a product that hangs for weeks; in a sausage smoked and eaten within days there's no time for it to do anything, so it just goes along for the ride.
2. The nitrite concentrations are twelve times apart. Cure #1 is 6.25% sodium nitrite. Tender Quick is 0.5%. Equal weights are nowhere near equal doses — that's the swap that gets people hurt.
3. Tender Quick is mostly salt and sugar. It's a complete curing system designed to season and cure at once, with whole cuts rinsed before cooking. Cure #1 is a concentrate that does one job and leaves the seasoning to you.
Morton's own directions for Tender Quick
If you're using Tender Quick, use it the way it was designed:
- Whole cuts: 1 tablespoon (½ oz) per pound of meat, rubbed in, bagged and refrigerated at 36–40°F for 4–8 hours, longer for thick cuts. Rinse before cooking.
- Ground meat: ½ tablespoon (1½ tsp) per pound.
- Brine: 1 cup dissolved in 4 cups of cool water, refrigerated, 24 hours.
So what should you actually do?
Use the cure your recipe was written for. If the recipe says Cure #1, use Cure #1 — it's cheap, it's everywhere, and it's what the numbers in that recipe assume. If all you have is Tender Quick, find a recipe written for Tender Quick rather than converting one.
Cure is the one ingredient in sausage making where improvising is genuinely unsafe rather than just disappointing. Everything else is a texture or flavour decision. This one isn't.
Bottom line
Tender Quick and Cure #1 are not interchangeable. Cure #1 is 6.25% nitrite dosed at 0.25% of meat weight (1.13 g per pound) and adds no meaningful salt. Tender Quick is 0.5% nitrite plus 0.5% nitrate in a base of salt and sugar, and at its own directions it adds about 3.1% salt. Match the cure to the recipe.

Common questions
Can I substitute Tender Quick for Cure #1?
Not by swapping one for the other in a recipe. They are built for different jobs. Cure #1 is 6.25% sodium nitrite and is dosed at 0.25% of the meat weight, about 1.13 g per pound, adding almost no salt of its own, so the recipe adds salt separately. Morton Tender Quick is mostly salt and sugar with 0.5% sodium nitrite and 0.5% sodium nitrate, and at its own directions it adds about 3.1% salt to the meat. Swapping by weight either wildly over-salts the batch or leaves it under-cured. Use the cure the recipe was written for.
What is the difference between Tender Quick and Cure #1?
Cure #1, also called Prague Powder #1 or pink curing salt, is 6.25% sodium nitrite and 93.75% salt, and contains no nitrate. Morton Tender Quick is a complete cure mix: salt, sugar, 0.5% sodium nitrite and 0.5% sodium nitrate. The nitrate is the important difference. Nitrate breaks down slowly into nitrite over a long cure, which is useful for some products and pointless in a sausage that is smoked and eaten within days.
How much Tender Quick per pound of meat?
Morton's own directions are 1 tablespoon, which is half an ounce or about 14 grams, per pound of meat for whole cuts, and half a tablespoon, about 1.5 teaspoons, per pound for ground meat. Whole cuts are rinsed before cooking; ground meat is not. Follow Morton's directions for Tender Quick rather than adapting a Cure #1 recipe.
Does Tender Quick give the same amount of nitrite as Cure #1?
Not at the ground meat rate. Cure #1 at the standard 0.25% of meat weight delivers about 156 ppm of ingoing nitrite. Tender Quick at Morton's whole cut rate of a level tablespoon per pound lands at roughly the same 156 ppm, but at the ground meat rate of half a tablespoon it delivers only about 78 ppm, roughly half. It also adds nitrate in both cases, which Cure #1 does not contain.
What is Peklosol and how does it compare?
Peklosol is the Polish curing salt, about 0.6% sodium nitrite and 99.4% salt. Like Tender Quick it is a salt replacement rather than an additive: to reach roughly 156 ppm of nitrite you would use about 11.8 g per pound, and that alone puts about 2.5% salt into the meat. That is close to a normal sausage salt level, which is the point. It is not interchangeable with Cure #1 by weight.
What should I do if I only have Tender Quick?
Use a recipe written for Tender Quick, following Morton's directions, rather than converting a Cure #1 recipe. Cure is the one ingredient where improvising is genuinely unsafe, and the two products distribute salt so differently that a converted recipe rarely lands where you expect on either salt or nitrite.
