I've been making a lot of pork/beef sausages over the last few months and have a recipe down that I like, but now I'm about to transition to making some game sausages since it's that time of year, and am unsure on what percentages of venison to pork shoulder to use. I've been using 70% pork butt and 30% brisket for my sausage, but wonder if I need to up my pork shoulder significantly to account for the lack of fat in venison, maybe 50/50? Going to post to outdoors too, but wanted to start here. Thanks.
