Biscuits and gravy is a popular breakfast dish in the United States, especially in the South. The dish consists of soft dough biscuits covered in white sausage gravy, made from the drippings of cooked pork sausage, flour, milk, and often (but not always) bits of sausage, bacon, ground beef, or other meat. The gravy is often flavored with black pepper; see Sausage gravy.
A variation of the dish served in the US military is sometimes referred to as "SOS", which means "shit on a shingle", and is prepared with either biscuits or toast. It has been a staple military comfort food for over 100 years.
