Sausage

Sausages consist of ground meat and other animal parts, herbs and spices, and possibly other ingredients, generally packed in a casing (traditionally the intestines of the animal), and preserved in some way.

There is no consensus whether similar products that are not packed in casings, such as pâté, meatloaf, scrapple and head cheese should be considered sausages. Pieces of sausage &mdash;often not including casing&mdash;are a popular topping for pizza in many countries.

Professor Amelia Rumford was fond of sausage sandwiches, believeing that eating them helped one think ("The Stones of Blood"). Sausages and Mash were mentioned by the Doctor as being what Rose Tyler would be eating if she left the TARDIS, along with fish and chips, beans on toast, turkey and nut loaf ("Children In Need Special").
