"Ketwurst is a form of hot dog created in the German Democratic Republic. The word \"Ketwurst\" comes from a combination of Ketchup and Wurst (German for \"sausage\").Its preparation involves the heating of a special Bockwurst, larger than regular hot dogs, in water. A long roll is pierced by a hot metal cylinder, which creates an appropriate sized hole."@en . . . . . . "Ketwurst"@en . . "Bread roll,bockwurst,ketchup" . .
