Seasoned sausagemeat that instead of being stuffed into a casing to make regular sausages with, has been formed into a roll. The sausagemeat is usually made of pork, but may be beef, lamb, turkey or chicken, or even venison. There are many different brands, offering many different flavours such as plain or sage. Some varieties, such as those from Virginia, contain large portions of fat on purpose.
It is often used to make Biscuits and Gravy in the American south.
You slice it up into patties and fry them up, or crumble slices up and fry as needed for given recipes.
