A natural sausage casing is a sausage covering made from cleaned animal intestines or other suitable natural membranes. It holds the filling during stuffing and processing and contributes the traditional bite, appearance and texture associated with many fresh, cooked and cured sausages. Natural casings vary in diameter, strength and texture according to their animal source and preparation.
Natural casings are often supplied salted or packed in brine. Follow the supplier’s instructions for rinsing, soaking and flushing before use. Check for tears, fit the casing onto the stuffing horn and fill evenly without excessive pressure. Overstuffing can cause the casing to split during linking or cooking.
Natural casings are animal-derived and are generally edible when properly prepared. Manufactured casings may be made from collagen, cellulose or plastic-based materials; some are edible and others must be removed. Never assume a casing is edible without checking its product specification.
Confirm the animal source, diameter, length, preparation requirements, storage conditions and intended use with the supplier. Keep casings under the storage conditions on the label and protect them from contamination. Sausage filling still requires appropriate refrigeration, sanitation and validated cooking or curing controls; the casing does not preserve unsafe meat.
Chef’s tip: Match casing diameter to the sausage style and stuffing equipment. Consistent casing size and fill weight help produce even links and predictable cooking results.
Key distinction: Natural casing is an animal-derived sausage covering. Collagen, cellulose and plastic casings are manufactured alternatives with different handling and eating characteristics.
