Which German sausage is protected as a specialty of Nuremberg and is usually made in small, thin links?

The sausage protected as a specialty of Nuremberg and made in small, thin links is Nürnberger Rostbratwurst.

These small grilled sausages are traditionally associated with Nuremberg, in Bavaria. Their protected geographical indication limits use of the name to sausages produced according to the recognized specifications in the defined area. They are made primarily from pork and are characteristically seasoned with marjoram.

Nürnberger Rostbratwurst is commonly served in groups, often with sauerkraut, potato salad, or horseradish. The name is sometimes confused with Thüringer Rostbratwurst, another German grilled sausage with its own regional identity and specifications.

The word Rostbratwurst refers to a sausage cooked on a grill or roasting surface. Its small size is one of the clearest features distinguishing the Nuremberg specialty from many larger German bratwursts.
