Want to make sausage but, don’t want to go through the hassle of flushing and cleaning Natural Casings only to have them burst on you later? Collagen casings are made from durable yet tender beef collagen which makes stuffing exceptionally easy. No soaking necessary (except for the flat variety) and each strand is surprisingly long when stuffed due to its accordion form. Get uniform diameter links and fewer casing bursts. Strand Collagen casings are made of edible collagen while the flat collagen casings are non-edible but easy to peel-off the sausages when they are cooked/smoked.
