We had all of our link sausage made by the pros this year but did all of our pan sausage/hamburger meat on our own.
We've made our own pan sausage before, but this year it turned out the best we've ever made. Basically, what we did different this year than in years past:
1) use beef fat instead of pork fat, even for the pan sausage. In the past we've used pork fat for pan sausage and beef fat for burgers, but this year we used beef fat for all of it. Our local grocery store meat dept gives away the beef fat, so the price was right.
2) 80/20 lean to fat ratio. So, 2 lbs of fat for 8 lbs of venison/pork gave us 10 pounds of meat. We probably made close to 100 lbs between pan sausage and burger meat. In the past we've made it closer to 90/10, and it is so much better this go around.
As far as spices go, we used Zach's country style sage pork sausage seasoning.

It's easier to add more spice than to get it out.
Edit to add: my mom (who isn't much of a country gal, but is getting better every year) loves the venison hamburger meat and pan sausage we made, which is saying something considering she won't even eat the Jimmy Dean pan sausage. I think we convinced her that, at least with our homemade sausage, she was there every step of the way and knows exactly how it was made, which is more than she can say about any of the stuff from the store.
