We don’t run our meat quite par frozen, but our walk in cooler keeps it at about 1degree Celsius, and we only grind once then hand mix, because re grinding it is so hard on the grinder. You’re 100% on with the beef fat texture difference, the only reason we occasionally use it instead is some people don’t eat pork for religious reasons, for our all beef sausages or improving the texture on the goat and venison for our Jewish and Muslim clients.
Also if your vacuum sealing the sausages, it really helps to lay them out on trays and par freeze them before bagging, they handle easier and maintain their shape when sealed. Our machine will flatten them out completely if we try to package fresh. Pork casing wraps much easier in paper as well. But I just prefer the more “Dainty” sheep casing for chicken. We really should have a sausagemaking thread somewhere here for sharing recipes and techniques.
