I would make sure and have some of Pop's breakfast sausage spice mixed up and make at least a small about of it. Its totally outstanding breakfast sausage and it really simple. I always have a ball jar full of the made up spice. Most recipes will be for 5 or 10 lbs, you'll have extra left over.
I personally like a big butt, the fat content with few exceptions is usually right where I want it.
Again personal opinion, I have yet to find a turkey or chicken sausage I like, course I don't think I ever ate one till I started trying to make them.
There are loads of sausage recipes here nad easy to find using the search engine. Pick what you'll use, what you like and do it a couple a'times. Once to get your feet wet and then adjust to your own prefrences. AND keep a log somewhere so you know what you did so next time you don't need to start over again.
Its a lot of fun, make sure and read some of Roykjo's tutorials like how to handle casing. He's the 'spert around here. But lots of folks know their sausage making.
You can also get prepackaged kits from places like bass pro or cabelos etc..... they are also good for your first adventure too.
Bon Chance, and laissez les bons temps rouler!
