I have been making sausage for 30 years.
My venison sausage is better than any sausage you can buy in the store.
It is very hard to make up your own sausage seasoning. So I buy it from the RBH company in Starke Florida 1-800-964-4975.
You want Legg's Old Plantation Pork Sausage Seasoning.
The 8 ounce bag seasons 25 pounds of sausage.
One bag is $1.75. It will keep for a year. I go ahead and get three bags at once, they will keep for 3 or 4 years in the freezer.
You have to mix in beef fat or pork fat to make good sausage. Do not use any venison fat, venison fat does not taste good.
Mix one part fat to three parts venison.
I have a grocery store that saves fat for me, and gives it to me for free. You can go ahead and get the fat early, and freeze it. It is ok to freeze the fat, then defrost to make sausage, then freeze the sausage.
You need to grind sausage twice to get the right consistency.
As for the weight, if you don't have a scale, which I don't, I just estimate.
I have a big blue plastic two quart measuring cup.
I pack that with the cut up meat and fat.
It holds 4 pounds of water, I figure it holds 4 pounds of meat.
I fill that thing 3 times, I figure I have 12 pounds of meat.
I dump the whole bag of seasoning out onto a big plate.
I cut it into two equal piles with a big knife. I just dump one of the piles into the 12 pounds of meat and fat.
Mix this in well for the first grind.
Fry up a patty and see how you like it. You might want it hotter, just add a few tablespoons of cayenne pepper. Mix the pepper in thoroughly. Then, do the second grind.
I have made many hundreds of pounds of venison sausage. Yes it is a mess, and it is a lot of trouble, but it is worth it to make such delicious sausage.
