Cure #1 and Cure #2 both come in small packets. Both are dyed pink. Both sit in the curing salts section, and if you pick one up without reading the label, you'd have no way to tell them apart. They are not the same product. One is designed for cured meats that get cooked. The other is designed for salami, prosciutto, and anything that air-dries for weeks or months without ever hitting heat. Using the wrong one isn't a flavour call — it's a food-safety issue.
What Cure #1 does
Cure #1 — also sold as Prague Powder #1, Instacure #1, or pink curing salt — is 93.75% salt and 6.25% sodium nitrite. Sodium nitrite is the active cure. It inhibits bacterial growth during the curing process, sets the characteristic pink colour, and contributes the flavour you associate with bacon and ham.
The design is intentional. Sodium nitrite breaks down at cooking temperatures. When you hot smoke a bacon belly or roast a leg ham, the nitrite converts and does its job. By the time the product comes off the heat, it has been used up. That is what makes Cure #1 right for anything that will be cooked or smoked before eating.
It is the correct cure for bacon — belly, back, or loin — cured ham and Christmas ham, pastrami, corned beef, and kranskys or any cured sausage that gets cooked before it is eaten. If the product goes into the oven or the smoker, Cure #1 is what you want.
On dosing: follow the exact quantities in your recipe and weigh on digital scales. Do not estimate curing salts.
What Cure #2 does
Cure #2 contains 89.75% salt, 6.25% sodium nitrite, and 4% sodium nitrate. That third ingredient — sodium nitrate — is the difference between a short cure and a long one.
Sodium nitrate is a slow-release reservoir. Over weeks and months of air-drying, it breaks down gradually into sodium nitrite, providing ongoing bacterial protection throughout a curing process that can run for two to four months. A salami is never cooked. It ferments, dries, and is eaten as it is. For a product like that, you need a cure that stays active the whole way through — and that is what the nitrate provides.
Cure #2 is for salami of every type — Hungarian, Calabrese, cacciatore — prosciutto and other long-cured whole-muscle cuts, pancetta, and coppa. Any product that ferments, air-dries, and is eaten without cooking needs Cure #2.
On dosing: 2.5g per 1kg of meat for most salami recipes. Weigh on digital scales. Follow a tested recipe exactly. This is not a number to adjust.
Why you cannot swap them
This is the part that matters.
Cure #1 in a salami: sodium nitrite breaks down quickly — it is designed to. A salami that dries for six weeks without being cooked ends up with no active cure protection by the time it is half-dry. That leaves a long-air-dried product without the bacterial inhibition it needs. The specific risk is Clostridium botulinum. This is not theoretical.
Cure #2 in a bacon: the sodium nitrate it contains needs time to convert — it is a slow-release mechanism built for months of drying, not days. Bacon is cured over a short period and then cooked. The slow-release component has no time to do its job, and the dosing and safety parameters are different from Cure #1.
Both cures are dyed pink so they cannot be confused with table salt. That does not make them interchangeable.
The rule is straightforward: if it gets cooked or hot-smoked before eating, use Cure #1. If it air-dries and is eaten without cooking, use Cure #2.
FAQ
What's the difference between Cure #1 and Prague Powder #1?
Same thing. Prague Powder #1, Instacure #1, pink curing salt, and Cure #1 are all names for the same product — 93.75% salt and 6.25% sodium nitrite. Different brands use different names; the formulation is the same.
Can I use Cure #2 for bacon?
No. Cure #2 is designed for long air-dried products. The sodium nitrate it contains needs weeks to convert to active nitrite — it is not built for a short cure followed by cooking. For bacon, use Cure #1.
What happens if I use Cure #1 in a salami?
Sodium nitrite breaks down during the dry. By the time the salami has been hanging for a few weeks, the active protection from Cure #1 is largely gone. A long-air-dried product that loses its cure protection partway through the process creates a genuine food-safety risk. Use Cure #2 for all salami.
How much do I use?
Dosing varies by product and recipe — follow the quantities your recipe specifies. For salami using Cure #2, 2.5g per 1kg of meat is the standard starting point in most tested recipes. For Cure #1, the rate depends on the product and method, so check your recipe. Weigh on digital scales and do not estimate curing salts.
Do I need both Cure #1 and Cure #2?
If you make both cooked-cured products and air-dried products, yes. They are not interchangeable and one cannot substitute for the other. If you only make bacon, you only need Cure #1. If you only make salami, you only need Cure #2.
Are curing salts safe to handle?
Both are used in small, weighed quantities and are safe when correctly applied in food preparation. The pink dye exists specifically so they cannot be confused with table salt. Store them clearly labelled, away from other ingredients, and out of reach of children and pets
