Several years ago my father-in-law gave us his recipe for hamburger sausage. It is like summer sausage - but much better than the store bought items. I decided that this recipe should be the one I post for The Grocery Cart Challenge recipe swap. It is so easy to make (it does take a total of 3 days to finish the sausage though) and it does make 3 rolls out of each batch. Keep 1 and give 2 away as gifts if you'd like. With a box of crackers and a cute bag - perfect!
5 lb hamburger (you want it to have some fat, 70-80% is perfect)
3 tsp garlic salt
4 1/2 tsp pepper
4 1/2 tsp mustard seed (I usually add a bit extra though)
2 tsp liquid smoke
5 heaping tsp Morton Tender Quick
Mix all ingredients together. Place in doubled plastic bags. Refrigerate for 3 days, remove & knead each day. On the 3rd day knead & shape into 3 rolls. Bake on a broiler tray for 8 hours at 150 degrees.
The reason for the double bags is to make sure it stays sealed well. When you cook it you need the broiler tray so the excess fat can drain. After you have cooked it either refrigerate it or freeze it.
