What kind of sausage? Summer sausage? Snack sticks? If you want to give it a try I suggest running to Scheels or Fleet Farm and pick up a sausage kit that’ll do maybe 5 or ten pounds that also includes the casings, otherwise attempting to piece together everything you need is going to be pretty expensive. Weigh your meat and buy pork shoulder to match that weight and get enough kit to do that amount of sausage. Follow the kit’s directions. Decide if you think that you want to expand your horizons from there.
I’ve been making my own sausage for almost 40 years and have the grinder and stuffer and use commercial seasonings from Waltons.com. I often end up with extra trim and simply use the High Mountain seasonings that these stores sell to use the meat up and will give the chubs or whatever sausage I’ve made away to friend.
If you’re thinking of jerky you have two directions to go: cut muscle or ground and pressed. I don’t do the ground stuff. I make cut muscle and its by far a nice jerky. Again you can start by buying the seasonings at either of the mentioned store that will make 2 to 10 pounds. Trim away all of the fat on any jerky meat and do not mix with pork if you are doing the ground variety.
Take your time and make keeping things clean a priority and I think you’ll find making your own sausage/jerky quite rewarding.
