Regensburger Wurst is a boiled sausage with a fine or coarse pork filling. It comes in a compact shape with a length of about 10 cm and a diameter of about 4 cm. It was invented in Regensburg in the second half of the 19th century and only sausages that are produced in the inner city ring may be called "Regensburger". The local name for the sausages is "Knacker", which can be translated as "cracker" or "crackler".
