A sausage casing is the tubular covering that holds ground or chopped sausage filling in shape during stuffing, linking, cooking, drying or curing. Casings may be natural or manufactured from collagen, cellulose or other approved materials. The correct casing depends on the sausage style, diameter, production method and whether the casing is intended to be eaten or removed.
Casings are selected by diameter, strength, permeability, processing temperature and the intended finished product. Small sheep casings are common for thin links, hog casings for many fresh sausages, and larger beef or manufactured casings for selected salami and cooked products. The exact application depends on the casing grade and supplier instructions.
Prepare casings according to the manufacturer’s instructions. Natural casings are often salted and require rinsing, soaking and flushing before use. Fit the casing onto the stuffing horn, fill evenly and avoid excessive pressure. Link or tie the sausage without stretching or damaging the casing.
Keep casings and sausage filling under appropriate refrigerated conditions, prevent cross-contamination and follow validated time, temperature, curing and cooking controls. A casing does not make sausage safe to eat raw or undercooked. Confirm whether a manufactured casing is edible before serving.
Chef’s tip: Standardize casing diameter, fill weight and link length. This improves portion consistency and helps sausages cook or cure evenly.
Key distinction: “Casing” is the general term for the sausage covering. Natural casing is one specific type, not a synonym for every sausage casing.
This term is one of hundreds covered in depth across OCS courses, learning paths, and 1-on-1 coaching with Chef Eric.
