We call the Snags here in Australia , and as @arty zan said can be low in meat , where it tricks you is the classification of meat , it is not what you think as meat , can and doe's consist of skin - tendons - jowl [ cheek meat ] intestines all are classified as meat , The easy way to know if you have a good sausage is by the texture , very fine sausages have been done with a bowl cutter , which is a bowl with high speed cutting knifes to cut and mix the meat together , then soy products are added to bulk out the sausage filling , I good sausage has a lot more of a coarse texture , first run thru a 10mm plate , then herbs ect added - binders then water and mixed well , then thru the 5 mm , I make around 200 kg a week , Pork - Beef - Lamb - in 30 years there is not much I have not made into a sausage - Croc - duck - swan - buffalo - kangaroo - Fish - Venison - Ostrich - Emu - Chicken ect . I find 25 % fat to 75% meat [ real meat ] will give you a good healthy sausage .
