ink Curing Salt: Cure #1 vs Cure #2 Explained

Pink curing salt is a curing salt blend made from regular salt plus a measured amount of sodium nitrite, or sodium nitrite and sodium nitrate, depending on whether it is Cure #1 or Cure #2. It is not the same as Himalayan pink salt, and it should never be used like normal table salt.

In meat curing, pink curing salt is used in very small, carefully measured amounts. It helps develop the familiar cured color and flavor in products like bacon, pastrami, ham, corned beef, salami, pancetta, coppa, and bresaola.

I have used curing salts in many home curing projects over the years, from small bacon pieces to longer whole-muscle dry cures. The main lesson is simple: pink curing salt is useful, but only when it is weighed accurately and used for the right type of cure.

The two main types are Cure #1 and Cure #2. Cure #1 is generally used for shorter curing projects that are cooked, smoked, or finished within a shorter timeframe. Cure #2 is used for longer dry curing projects where nitrate slowly converts into nitrite over time.

This distinction matters because the two curing salts are not interchangeable. Using the wrong one can change the curing process, the flavor, the color, and the way the meat develops during drying or cooking.

Pink Curing Salt #1 vs #2

The easiest way to understand pink curing salt is to compare Cure #1 and Cure #2 side by side. Both are mixed with regular salt and dyed pink to avoid confusion with table salt, but they are designed for different curing timelines.

Type	Contains	Typical Use	Common Projects
Pink Curing Salt #1	Salt plus sodium nitrite	Shorter cures, often under 30 days, especially products that are cooked or smoked	Bacon, pastrami, corned beef, ham-style cures, some sausages
Pink Curing Salt #2	Salt plus sodium nitrite and sodium nitrate	Longer dry cures where the meat dries over weeks or months	Salami, bresaola, coppa, pancetta, long dry-cured whole muscle meats

For beginners, Cure #1 is usually the curing salt you see in bacon, smoked meats, and shorter curing recipes. Cure #2 belongs in longer dry-curing projects where the meat is not simply cured and cooked quickly.

I always decide which curing salt to use based on the project first, not just what I have in the cupboard. A bacon recipe, a pastrami cure, and a long dry-cured bresaola are not the same type of curing process.

What Is Pink Curing Salt?

Pink curing salt is a standardized curing mix used in meat curing. It is made from regular salt blended with a controlled amount of sodium nitrite, or sodium nitrite and sodium nitrate, depending on the type.

The pink color is not from minerals. It is a food-safe dye added so that curing salt is not mistaken for normal salt in the kitchen.

That distinction is important. Pink curing salt is not Himalayan pink salt, pink sea salt, or any kind of gourmet finishing salt. Himalayan salt is primarily sodium chloride with trace minerals, while pink curing salt contains nitrites or nitrates for specific curing purposes.

I have seen this confusion arise many times among beginners. The word “pink” causes the problem, because one product is pink from dye and the other is naturally pink from minerals.

They are not substitutes for each other. If a recipe calls for pink curing salt, it refers to curing salt, Prague powder, Instacure, or a similar curing mix — not Himalayan salt.

If you want a broader salt comparison, I cover sea salt, kosher salt, table salt, Himalayan salt, and curing salt in my guide to choosing the right salt for meat curing.

Why Pink Curing Salt Is Used

Pink curing salt is used in established curing methods to develop cured color and flavor and to achieve a more predictable result. It is especially common in bacon, ham, pastrami, corned beef, some sausages, and long dry-cured meats.

In short cures, Cure #1 supplies nitrite directly. In longer dry cures, Cure #2 also includes nitrate, which gradually converts to nitrite during the drying period.

The curing salt does not do the whole job by itself. Good curing still depends on accurate salt percentages, clean handling, correct time, suitable temperature, airflow, humidity, and the right method for the meat being cured.

That is why I use curing salt as one part of a complete process, not as a shortcut. It works best when the entire cure is properly planned.

Why Meat Turns Pink When Cured

The pink color in cured meat comes from a reaction between nitrite and myoglobin, which is the natural pigment in meat. This reaction helps create the familiar rosy cured color you see in bacon, ham, pastrami, and corned beef.

Without nitrite or nitrate, cured meat often looks duller, browner, or more naturally meat-colored. That can be completely normal for certain traditional salt-only cures, but it looks different from classic cured bacon or ham.

I do make some salt-only cures, especially for certain whole-muscle projects. But when I want the traditional cured color and flavor of bacon or pastrami, I use the correct curing salt and weigh it carefully.

Do You Have to Use Pink Curing Salt?

You do not have to use pink curing salt for every cured meat project. Some traditional whole muscle dry cures can be made with sea salt, time, airflow, and controlled drying, depending on the method and the style of cured meat.

But pink curing salt is commonly used in many established curing methods, especially for bacon, ham-style cures, pastrami, corned beef, smoked meats, fermented sausages, and long dry-cured meats.

The decision depends on the project. I do not treat curing salt as mandatory for every piece of meat, but I also do not ignore it when the recipe, curing environment, or traditional method calls for it.

For example, I am more likely to use Cure #1 for bacon or pastrami, and Cure #2 for long dry-cured projects like bresaola, coppa, pancetta, or salami-style curing. For some small, salt-only whole-muscle projects, I may choose not to use it.

If you are unsure whether your project needs it, the safest approach is to follow a proven recipe from a reliable curing source and match the curing salt type to the method.

How Much Pink Curing Salt Do You Use?

For standard American-style pink curing salt at 6.25% sodium nitrite, the common home-curing amount is 0.25% of the meat weight. That means 2.5 grams of pink curing salt for 1 kilogram of meat.

This is why accurate weighing matters. Pink curing salt is used in small amounts, so teaspoons, pinches, and rough scoops are not accurate enough for the way I cure meat.

Meat Weight	Pink Curing Salt at 0.25%
500 g	1.25 g
1 kg	2.5 g
2 kg	5 g
5 kg	12.5 g
10 kg	25 g

When I use equilibrium curing, I calculate the curing salt as part of the total cure. For example, if I want 3% total salt for a dry-cured meat project, I might use 2.75% sea salt plus 0.25% pink curing salt.

The calculator makes this easier, especially when working with different meat weights. My equilibrium curing calculator is designed for this percentage-based curing style.

How I Use Pink Curing Salt Accurately

Once I know whether a project needs Cure #1 or Cure #2, the next step is accuracy. I always weigh curing salt in grams because the amounts are small and the difference between correct and excessive can be tiny.

For home curing, I prefer percentage-based curing because it scales to any size piece of meat. A 500 g piece of pork belly and a 3 kg ham-style cure need different amounts, but the same percentage method works for both.

The simple rule I use with standard pink curing salt is 0.25% of the meat weight. Then I add the rest of the salt separately, depending on whether I want a mild bacon cure, a stronger dry cure, or a long drying project.

This is where many curing mistakes happen. Pink curing salt is not the total salt in the recipe. It is one part of the total cure, alongside sea salt, sugar, spices, herbs, or other flavorings.

Equilibrium Curing Method

Equilibrium curing is my preferred method because it removes a lot of guesswork. Instead of covering meat with excess salt and hoping the timing is right, the salt is calculated from the meat’s weight at the start.

For example, if I cure 1 kg of meat with 3% total salt, that amounts to 30 g of salt. If I am using 0.25% pink curing salt, that is 2.5 g curing salt plus 27.5 g regular salt.

The meat is then sealed with the cure and left long enough for the salt to distribute evenly. This yields a more predictable result than guessing based on time alone.

Equilibrium curing also helps prevent over-salting because the meat only has access to the amount of salt you calculated. This is why I use it so often for bacon, pancetta, bresaola, coppa, and many whole-muscle projects.

If you want the full method, I explain it separately in my complete guide to equilibrium curing meat.

Dry Cure vs Brine Cure

Pink curing salt can be used in both dry curing and brining, but the calculation has to match the method. A dry cure is rubbed directly onto the meat, while a brine dissolves the salt and curing salt into water.

For dry curing, I calculate the cure based on the meat weight. For equilibrium brining, I calculate based on the meat and water together, because the salt moves through both.

Method	How Pink Curing Salt Is Used	Best For
Dry Cure	Mixed with regular salt and rubbed directly onto the meat	Bacon, pancetta, bresaola, coppa, small whole muscle cures
Wet Brine	Dissolved into water with salt, sugar, and spices	Ham-style cures, corned beef, pastrami, larger pieces, some bacon

Both methods can work well. The important part is not whether the cure is wet or dry, but whether the curing salt has been calculated correctly for that method.

I compare the two methods in more detail in my guide to dry curing vs wet brining for meat curing.

Why Accurate Scales Matter

Because pink curing salt is used in such small quantities, a reliable digital scale is one of the most important tools for curing. I prefer a scale that reads to at least 0.1 g, and for very small batches, 0.01 g is even better.

I do not use teaspoons for precise curing salt calculations. A teaspoon can vary depending on the grain size, how it is scooped, and whether it is level or rounded.

Weighing removes that uncertainty. It also makes the recipe repeatable, which is one of the main reasons my curing improved over time.

Safety, Regulations, and Nitrite Facts

Pink curing salt is used in established curing methods because nitrite and nitrate have specific roles in cured meat. They help develop cured color and flavor, and they are also used in controlled curing systems where unwanted bacteria are a concern.

That does not mean curing salt does everything on its own. Good curing also depends on clean handling, accurate salt levels, correct time, suitable temperature, airflow, humidity, and the right process for the meat being cured.

The important point is measurement. Standard pink curing salt #1 in the United States contains 6.25% sodium nitrite. Because that concentration is standardized, home curers can calculate small amounts accurately when using percentage-based recipes.

The USDA curing guidelines provide technical information on the use of nitrite in cured meat. The European Food Safety Authority also publishes information on nitrate and nitrite limits and risk assessment.

I use those types of references as background, but for home curing, I keep the practical rule simple: use the correct curing salt, weigh it accurately, and follow a proven curing method rather than guessing.

Nitrite, Nitrate, and Food Context

Nitrite and nitrate are not only found in cured meat. They also occur naturally in vegetables and drinking water. That broader food context is useful, but it does not change the need to measure curing salt properly when making cured meat.

For me, the useful takeaway is not that more is better. It is the opposite. Curing salt is effective because it is used in small, controlled amounts as part of a complete curing process.

When I use it in bacon, pastrami, pancetta, bresaola, or salami-style projects, I weigh the curing salt separately and mix it thoroughly with the rest of the cure before it comes into contact with the meat.

Precautions When Using Pink Curing Salt

Because pink curing salt is powerful in small quantities, I never estimate it by eye. I also keep it labeled clearly and stored away from normal salt, so it cannot be used accidentally at the table or in everyday cooking.

It is also worth repeating that pink curing salt is not interchangeable with Himalayan pink salt, sea salt, kosher salt, or table salt. Those salts may be useful in curing for flavor and salinity, but they do not contain the same blend of nitrite and nitrate.

If the wrong amount is used, the result can be patchy color, harsh flavor, excessive saltiness, or a cure that does not behave as expected. This is why I rely on percentages, accurate scales, and repeatable recipes.

For small home batches, the amount of curing salt can be only a few grams. That small amount needs to be mixed evenly into the rest of the salt, sugar, and spices so the cure is properly distributed.

Temperature and Cooking Considerations

High heat is another reason to understand the curing process. Nitrosamines can form when cured meats are exposed to very high temperatures, especially during intense frying or grilling.

For this reason, I avoid burning or aggressively frying cured meats. Air drying, cold smoking, gentle cooking, and careful pan cooking are very different from charring cured meat at high heat.

With bacon, for example, I prefer cooking it gently rather than blasting it until burnt. It tastes better, and it keeps the process more aligned with how cured meat is traditionally handled.

Different Names for Pink Curing Salt

Pink curing salt is sold under several names. The label can vary by country, brand, and supplier, but the important part is knowing whether the product is made for short cures or long dry cures.

In North America, the common names are Prague Powder, Instacure, Tinted Curing Mix, Cure #1, and Cure #2. These are the names most home-curing recipes use for standard pink curing salt.

Short Cures	Long Dry Cures
Prague Powder #1	Prague Powder #2
Instacure #1	Instacure #2
Tinted Curing Mix #1	Tinted Curing Mix #2
Cure #1	Cure #2

The key is not the brand name. The key is the nitrite and nitrate content. Cure #1 is used for shorter cures, while Cure #2 is used for longer-drying projects where nitrate has time to convert during curing.

Some European and international curing salts use different nitrite levels from American-style pink curing salt. For example, certain nitrite salts are blended at much lower percentages and are used differently.

This is why I always check the label before calculating a cure. My percentage examples in this article are based on standard 6.25% sodium nitrite pink curing salt, not every curing salt sold worldwide.

If you are using a local curing salt blend, follow the supplier’s instructions and local food standards. Do not assume that every pink, nitrite, or curing salt product is calculated the same way.

Useful References and Further Reading

For technical information, the USDA curing guidelines are useful for understanding nitrite use in meat processing. The European Food Safety Authority also publishes information on nitrate and nitrite risk assessment.

For a practical home-curing perspective, I still think books are worth reading. My list of useful meat-curing books includes references that explain both traditional and modern curing methods in more depth.

The big picture is this: pink curing salt is a precise curing ingredient, not a general seasoning. Used correctly, it helps with cured color, flavor, and consistency. Used casually, it can create problems.

That is why my own approach is always the same. Choose the right curing salt, weigh it accurately, mix it evenly, and use it as part of a complete curing method rather than relying on it by itself.
