Curing Meat for Sausages

Let’s make something absolutely clear, you don’t need to cure meat to make your sausage. Grind the meat, mix with spices and stuff the mass into a casing. Grill it, hot smoke it, or place it in a refrigerator, the product is still called a sausage. Curing is an extra process that requires more time, designated containers and a space in a refrigerator. The reason we advocate the curing procedure is that this book is about making quality products and quality takes time. Meat for quality smoked sausage should be cured. Curing imparts a certain peculiar flavor which is in demand by the consumer and if we cure hams, bacon, chops, butts, and fish because they taste better, so why not cure meat for sausages? The fact that we grind meat makes it only easier on our teeth to chew it - it does not improve the color, texture or the flavor of the sausage. Someone might say: but I’ve mixed nitrite and spices with ground meat before stuffing so that’s OK. Well, it’s not ok, the problem is that not enough time was allocated and the sausage is only partially cured.

The dry method of curing is used to cure meat for sausages. Meat should be cut into smaller pieces, about 2 inches (5-6 cm) and not heavier than 0. 5 lb (250 g).

The curing time depends on:

Meat should be thoroughly mixed with salt, Cure #1 (salt, nitrite), sugar (if used) and packed tightly in a container, not higher than 8 inches (20 cm). Then the meat is covered with a clean cloth and stored in a refrigerator. There are chemical reactions taking place inside meat and the cloth allows the gases to evaporate through. It also prevents the surface of the meat from reacting with oxygen which sometimes creates gray color areas on the surface. This is normal, the meat is fine and there is nothing to worry about. With the use of ascorbates and erythorbates it is possible to cure meats at even lower temperatures, which is commonly practiced by commercial establishments. The curing times at 40° F (4° C) (refrigerator temperature) are as follows:

What will happen to smoked sausages if the meat is not cured? Basically nothing as long as you add salt and Cure #1 (sodium nitrite) to ground meat during mixing (you are still curing meat). The final color might not be as good as the properly cured sausage but it will still be a great sausage. If you don’t want to cure meat using the traditional method, use the alternative curing method described below.

Alternative curing methods

  1. Grind each meat through a proper plate (as dictated by the recipe). The reason that we grind now and not cut meat into pieces for curing is that salt and sodium nitrite will penetrate a tiny piece of ground meat much faster than a 5 cm (2”) cube. Mix meat with salt and Cure #1. Pack tightly (to remove air) and separately, place each type of ground meat in a container and cover with a cloth to allow breathing. Let it “set” for 3-4 hours at room temperature 20-22°C (68-71°F). Chemical reactions proceed much faster at higher temperatures and so does curing. Add spices, mix all together and stuff casings.
  2. Grind each meat through a proper plate (as dictated by the recipe). Mix meat with salt, Cure #1 and other ingredients. Stuff sausages and place in a cooler for 12-24 hours before smoking. When removed from a cooler they have to be conditioned at room temperature for a few hours to remove moisture from the surface.
  3. Grind each meat through a proper plate (as dictated by the recipe). Mix meat with salt, Cure #1 and other ingredients. Stuff sausages and hang at room temperature for 2 hours. Transfer to a smokehouse.

As you can see in all instances we are buying extra time to allow curing inside the meat. A commercial producer will not perform curing at higher than cooler temperature as this will affect the shelf life of the product. Commercial processors cure meat faster and at lower temperatures by using ascorbic acid, erythorbic acid, or their derivatives, sodium ascorbate and/or sodium erythorbate. These additives speed up the chemical conversion of nitrite to nitric oxide which in turn will react with meat myoglobin to create a pink color. They also deplete levels of meat oxygen which prevents the fading of the cured meat color in the presence of light and oxygen.

Bear in mind that those “simplified” curing methods can not be used when curing whole pieces like hams, butts or loins. Due to the insufficient curing time they will have an uneven pink and reddish area or even some gray in it. That would be easily noticeable when slicing those meats. As sausage is made from comminuted meat any variations in color can not be spotted, unless larger chunks of meat are mixed with finely ground meat.

When making less than 5 pounds of sausage it is perfectly acceptable to make curing a part of the mixing and conditioning process. This way the sausage is stuffed and ready to go into the smoker and all equipment can be washed and put away. When making large amounts of sausage, you may use a few pork butts or picnics and trimming this meat will take a while. Then you have to grind, mix, stuff and smoke sausages. This operation will take many hours. It is feasible to make sausages on two separate occasions:

  1. The first day - meat selection and trimming. The skin and bones are removed, all sinews, gristle and glands are discarded. Meat is cut into small pieces, mixed with salt and nitrite and placed in a refrigerator for 24 hours. Except the knife no equipment was needed.
  2. The second day - cured meat goes into the grinder and the sausage making process continues.
