It's weird to see the words "sausage" and "hamburger" used to describe the mince sausages and hamburgers are made out of. It's not a sausage until the mince is squeezed into a skin and made into long... sausages. It's not a hamburger until it's made into a patty for use in... hamburgers.
It's also weird that hamburgers are made of beef 99% of the time and not ham at all, but that's another story.
