A slang name for beef tartar. This is made from very finely chopped raw fillet of beef mixed with onion, gherkins (US: dill pickles) and capers and formed into the shape of a steak. A depression is made in the top into which a raw egg is broken. It is eaten raw. The meat really should not be minced (US: ground). It is thought to have originated with the fierce Tartars of the Baltic region of Russia who shredded the meat with a knife and ate it raw.
