A sauce boat, gravy boat, or saucière is a low jug or pitcher with a handle in which sauce or gravy is served. The typical shape is considered boat-like, hence the name. It often sits on a matching saucer, sometimes attached to the pitcher, to catch dripping sauce.
Some gravy boats also function as gravy separators, with a spout that pours from the bottom of the container, thus leaving any surface-floating fat in the container.
