chorizo casing

Hog casing is the material that’s used to enclose the filling that makes up a sausage. It’s made with pig intestines, specifically the sub-mucosa layer that’s composed mostly of collagen. Hog casings are natural, durable materials that have been used for many centuries, and they continue to be popular among sausage makers. Makers of homemade sausages also prefer them when producing their products.
