    How to stuff and link collagen casings at home

    Start with the correct casing type and its manufacturer’s instructions. Fresh edible collagen casings can usually be stuffed dry, while other types need different preparation. Gentle filling and limited twisting help prevent splits; safe sausage cooking is a separate requirement.

    Prepare the casing and equipment

    For the edible casings covered by LEM’s instructions, do not soak: load the casing onto a suitably sized stuffing tube as supplied. Clean the equipment and keep the meat mixture cold. Do not transfer these directions to collagen middles or non-edible casings, which have different preparation and removal requirements. [1][2]

    Fill evenly, then form the links gently

    Feed the mixture steadily and guide the casing without filling it beyond the recommended capacity. Leave enough flexibility for linking rather than making a tightly stretched tube. LEM advises only about one-and-a-half to two twists for its collagen casings; follow the exact product’s closing instructions and avoid repeated overtwisting. [1]

    Cook and store the sausage safely

    A successful casing does not make raw filling safe. USDA advises 160°F for uncooked beef, pork, lamb or veal sausage and 165°F for poultry sausage, checked with a thermometer. Imagine a link browns outside while the center is still cool: color is not the cooking check. Refrigerate promptly; this method is not a curing or shelf-stable drying recipe. [2]
