Quick Answer
When choosing the right size casings for different sausages, consider the type and size of the sausage, the desired texture, and the casings' material. Natural casings, like hog or lamb intestines, work best for traditional sausages like knockwurst and bratwurst, while collagen or cellulose casings are suitable for larger sausages like hot dogs. Measure the sausage's diameter to ensure a proper fit.
Choosing the Right Casing Material
Select casings based on the sausage type and desired texture. Natural casings, like hog or lamb intestines, provide a more traditional texture and flavor. They come in various sizes, from 16 to 24 mm (5/8 to 1 inch) in diameter. For example, use 16 mm casings for Italian sausage and 20 mm for knockwurst. Collagen or cellulose casings, on the other hand, are more flexible and suitable for larger sausages like hot dogs. They come in sizes ranging from 20 to 30 mm (3/4 to 1 1/4 inch) in diameter.
Casing Sizing Techniques
To ensure the right casing size, measure the sausage’s diameter using a casing gauge or a ruler. For natural casings, it’s essential to soak them in cold water for at least 30 minutes before use to rehydrate the material and make them pliable. Apply a thin layer of water or a lubricant, like glycerin, to the inner surface of the casing to prevent it from sticking to the sausage meat.
