Sausage
I thought making sausage was some kind of elite skill and avoided it for years. Turns out it's just ground meat with some seasonings!
You can use these sausage recipes free-form (no casing) or in casings as desired. For myself, I'm usually going to use the sausage in soups and other recipes so I go free-form, and honestly if I want a cased sausage I'll just buy it to avoid the hassle.
