Choosing the right sausage casing size is crucial for creating sausages that look appealing, cook evenly, and deliver the perfect bite. Get it wrong, and you might end up with sausages that burst during cooking, are too thin, or simply don’t have the desired texture. This guide will walk you through everything you need to know about sausage casing sizes, helping you select the perfect option for your next sausage-making adventure.
Understanding Sausage Casing Sizes and Types
Sausage casing sizes are typically measured by their diameter, usually in millimeters. This measurement refers to the width of the casing when it’s stuffed. Keep in mind that casing sizes can vary slightly between manufacturers, so it’s always a good idea to test a small portion before stuffing an entire batch.
Several types of casings are available, each with its own characteristics and ideal uses. The most common types are natural casings, collagen casings, and cellulose casings. Knowing the differences will help you pick the optimal size within each type.
Natural Casings: The Traditional Choice
Natural casings are made from the submucosa of animal intestines, typically hog, sheep, or beef. They offer a unique texture and “snap” that many sausage makers prefer. They also allow for good smoke penetration, making them a popular choice for smoked sausages.
-
Hog Casings: Hog casings are the most common type of natural casing. They are relatively strong and can be used for a wide variety of sausages, including bratwurst, Italian sausage, and Polish sausage. Hog casings typically range in size from 30mm to 42mm.
-
Sheep Casings: Sheep casings are more delicate than hog casings and are best suited for smaller sausages like breakfast sausages, frankfurters, and cocktail sausages. They provide a delicate snap and a tender bite. Sheep casings usually range in size from 19mm to 26mm.
-
Beef Casings: Beef casings are the largest of the natural casings and are typically used for large diameter sausages like bologna, summer sausage, and some types of salami. They are strong and can withstand longer cooking times. Beef casings can range from 43mm and upwards.
Collagen Casings: The Convenient Option
Collagen casings are made from the collagen found in animal hides. They are a convenient option for sausage making because they are pre-tubed and require no soaking. They are also relatively uniform in size, making them ideal for commercial sausage production.
-
Edible Collagen Casings: Edible collagen casings are designed to be eaten along with the sausage. They are available in a range of sizes and are often used for fresh sausages, smoked sausages, and cooked sausages. Sizes generally range from 16mm to 32mm.
-
Inedible Collagen Casings: Inedible collagen casings are stronger than edible casings and are typically used for dry sausages and salami. They are not meant to be eaten and should be peeled off before consumption. These can go to larger diameters, sometimes upwards of 100mm for large salami.
Cellulose Casings: The Versatile Choice
Cellulose casings are made from plant-based cellulose. They are strong and uniform in size, making them suitable for high-speed sausage production. They are also permeable to smoke, making them a good option for smoked sausages. However, they are typically peeled off after cooking.
-
Small Diameter Cellulose Casings: These are used for products like hot dogs and smaller smoked sausages.
-
Large Diameter Cellulose Casings: Used for products like large bologna and some types of liverwurst.
Choosing the Right Size for Your Sausage
The ideal sausage casing size depends on several factors, including the type of sausage you are making, the desired texture and appearance, and your personal preferences. Here’s a breakdown of common sausage types and their corresponding casing sizes:
Breakfast Sausage: Small and Snappy
For breakfast sausages, sheep casings (19mm to 26mm) are a popular choice. Their delicate snap and tender bite complement the flavors of breakfast sausage perfectly. Edible collagen casings in a similar size range are also a viable alternative.
Italian Sausage: Medium-Sized and Flavorful
Italian sausage typically uses hog casings (32mm to 38mm). This size allows for a good amount of filling and provides a satisfying bite. The natural casing also contributes to the authentic flavor and texture of Italian sausage.
Bratwurst: A German Classic
Bratwurst also commonly uses hog casings, typically in the 28mm to 32mm range. This size creates a plump, juicy sausage with a good snap. The slightly smaller size compared to Italian sausage can offer a slightly different eating experience.
Hot Dogs: Skinless or with a Snap
Hot dogs are often made with cellulose casings that are removed after cooking. However, natural sheep casings (19mm to 26mm) or small diameter collagen casings can also be used to create hot dogs with a natural snap.
Summer Sausage and Salami: Large and Impressive
Summer sausage and salami typically use beef casings or large diameter inedible collagen casings. The size depends on the desired diameter of the finished product, but it can range from 43mm to upwards of 100mm.
Factors to Consider When Choosing Size
-
Meat Block Texture: A coarser meat block may benefit from a slightly larger casing to prevent blowouts.
-
Cooking Method: Sausages that are grilled or pan-fried may benefit from slightly thicker casings.
-
Personal Preference: Ultimately, the best sausage casing size is the one that you and your customers enjoy the most. Experiment with different sizes to find your perfect match.
Tips for Working with Sausage Casings
Working with sausage casings can be a bit tricky, especially for beginners. Here are some tips to help you get the best results:
-
Soaking Natural Casings: Soak natural casings in warm water for at least 30 minutes before using them. This will help to rehydrate the casings and make them more pliable.
-
Inspecting Casings: Carefully inspect casings for any holes or tears before stuffing them. Discard any damaged casings.
-
Lubricating the Stuffer Horn: Lightly lubricate the stuffer horn with water or vegetable oil to help the casings slide on more easily.
-
Controlling the Stuffing Speed: Stuff the casings slowly and evenly to avoid air pockets.
-
Pricking Air Pockets: If you do encounter air pockets, use a clean needle or sausage pricker to release the air.
-
Twisting Sausages: To create links, twist the sausage at regular intervals. Alternate the direction of the twists to prevent the links from unraveling.
-
Storing Casings: Store unused casings in a cool, dry place. Natural casings can be stored in the refrigerator in a brine solution.
Where to Buy Sausage Casings
Sausage casings are available at a variety of sources, including:
-
Butcher Shops: Local butcher shops often carry a selection of natural casings.
-
Specialty Food Stores: Specialty food stores that cater to sausage makers often have a wider variety of casings.
-
Online Retailers: Many online retailers specialize in sausage-making supplies and offer a wide selection of casings at competitive prices.
When purchasing casings, be sure to check the expiration date and choose a reputable supplier.
Troubleshooting Common Problems
Even with careful planning, you may encounter some problems when making sausages. Here are some common issues and how to address them:
-
Sausages Bursting During Cooking: This can be caused by overstuffing the casings, using too much water in the sausage mixture, or cooking the sausages at too high of a temperature.
-
Sausages Being Too Dry: This can be caused by not using enough fat in the sausage mixture, overcooking the sausages, or using casings that are too thick.
-
Sausages Being Too Greasy: This can be caused by using too much fat in the sausage mixture or not cooking the sausages long enough.
-
Casings Being Difficult to Stuff: This can be caused by using casings that are too dry or using a stuffer horn that is too small.
By understanding the different types of sausage casings, choosing the right size for your sausage, and following these tips, you can create delicious and impressive sausages that will impress your friends and family. Experiment, have fun, and enjoy the process of crafting your own unique sausages.
What are the standard sausage casing sizes, and how are they measured?
Standard sausage casing sizes vary depending on the type of sausage you’re making. Hog casings typically range from 32mm to 38mm in diameter, ideal for bratwurst and Italian sausage. Sheep casings are smaller, usually between 18mm and 26mm, perfect for breakfast sausage and frankfurters. Beef casings are the largest, ranging from 43mm to over 65mm, used for bologna and summer sausage.
The measurement of sausage casings refers to their diameter when inflated, not their flat width. This diameter is typically expressed in millimeters. It’s important to choose the right size casing for the desired sausage, as too small a casing can burst during stuffing, while too large a casing may result in a loosely filled sausage.
How do I determine the correct casing size for a specific type of sausage?
The ideal casing size depends on the specific characteristics you want in your sausage. For example, if you’re making a coarse-ground bratwurst, a 35-38mm hog casing provides the necessary strength and texture. Conversely, a fine-textured breakfast sausage benefits from the delicate snap of a smaller 21-24mm sheep casing.
Researching recipes or referring to established sausage-making guides is the best approach. These resources often specify the recommended casing size for a particular sausage type. Experimentation can also play a role, especially if you are developing your own recipes. Keeping notes on your results will help you fine-tune your process over time.
What is the difference between natural and collagen sausage casings, and how does that affect size selection?
Natural casings are made from the submucosa of animal intestines, offering a unique texture and “snap.” They are permeable, allowing smoke and flavors to penetrate the sausage. Size selection with natural casings is crucial, as they can be more prone to bursting if overstuffed, requiring careful attention to filling.
Collagen casings are manufactured from collagen sourced from animal hides or bones. These casings are more uniform in size and strength than natural casings, often making them easier to work with for beginners. Collagen casings are available in edible and inedible varieties, and size selection is typically less critical due to their consistent elasticity and controlled production process.
Can I use a larger casing size than recommended? What are the potential consequences?
While using a larger casing size than recommended is possible, it often results in a less desirable final product. The sausage may lack firmness and have an uneven texture. The filling may not adhere properly to the casing, leading to air pockets and a visually unappealing appearance.
Furthermore, the cooking process can be affected. A larger casing might not shrink as tightly around the meat as a smaller one, potentially leading to a wrinkled appearance. The sausage may also take longer to cook thoroughly, increasing the risk of drying out the outer layers before the center reaches the desired temperature.
What happens if I use a casing that is too small for my sausage?
Using a casing that is too small for your sausage is a recipe for disaster. The most common consequence is bursting during the stuffing process. The excessive pressure of the filling can easily exceed the casing’s capacity, leading to a messy and frustrating experience.
Even if the casing doesn’t burst during stuffing, it’s likely to do so during cooking. The heat causes the sausage to expand, placing further stress on the already stretched casing. This can result in an unevenly cooked sausage and a significant loss of juices and flavor.
How do I prepare sausage casings before stuffing, and does preparation affect size and usability?
Proper preparation is crucial for both natural and collagen casings. Natural casings require rinsing inside and out to remove excess salt and debris. They also need to be soaked in warm water for at least 30 minutes to rehydrate and become more pliable. This rehydration process allows the casing to stretch and accommodate the filling without tearing easily.
Collagen casings typically don’t require soaking, but it’s still a good idea to check the manufacturer’s instructions. Some collagen casings might benefit from a brief soak in lukewarm water to improve their flexibility. Regardless of the type, ensuring the casings are clean and pliable is vital for successful stuffing and a high-quality finished product.
Are there tools available to help me determine the correct casing size, or to make stuffing easier with different sizes?
While there aren’t specific tools designed solely to determine the correct casing size (as that depends on the recipe and desired outcome), there are tools that simplify the stuffing process, especially when dealing with varying casing sizes. Sausage stuffers with different nozzle sizes are essential. These nozzles allow you to control the flow of meat into the casing and accommodate different casing diameters.
Additionally, casing crimpers or tiers can help secure the ends of sausages effectively, regardless of size. Consistent crimping or tying ensures that the sausage filling remains contained during cooking. Some online resources offer guides or charts linking sausage types to suggested casing sizes, which can provide a helpful starting point.
