Whew... long day of making sausage. We did several pounds of Italian and Chorizo sausage. I didn't document the chorizo, but here's how we did the Italian.
Sausage casings: Use all natural casings. The fibrous one are junk. Also, don't buy you casings from Bass Pro etc. I have had problems with their casings tearing very easily. I'm not sure, may they set on the shelves too long or something. I get mine from a local meat market.
Pork fat: We used pork fat back from Newman farms which is heritage Berkshire pork raised 100% outdoors on pastures. I get this at the Farmer's market in the summer and freeze it until needed.
Seasonings: Use the freshest seasonings possible. Seasonings that sit on your shelf for months and months or even years, tend to turn into sawdust, especially after you freeze them.
Step 1: Grind your venison
Step 2: Grind the pork fat

Step 3: Blend the fat and venison. I do this buy sight, basically eyeball a 3-1 ration of venison to fat.

Step 4: Season.

I used the following:
Roasted Fennel (very important. You'll have to roast it yourself)
Red pepper
Salt
Italian Herb
Cayenne
Anise Seed
Roasted Garlic Paprika
Red Wine Vinegar
Other items you could also use:
Onion
Red Wine
Mace
Anything else that sounds good.
Be very generous with the quantities. You'll want a skillet going and make sample patties until you reach the desired flavor profile.
Step 4: Stuff the casings

Step 5: Twist at desired intervals

Step 6: Eat and enjoy!
