This fish shop sold Schillerlocken (on the right), a term I had not associated with fish. Schiller, of course, made me think of Friedrich Schiller, and Locken are curls.

* Where does this term come from?

The term is coined after its resemblance to Friedrich Schiller’s long curls.

* What are Schillerlocken?

This part is the belly side of the Dornhai (Hai: shark), one of the shark species.

* How do you eat them?

I observed a family of four ordering four Schillerlocken, which then were served in a German bread roll and they were also offered the Danish curry sauce, which they declined.

I have never tried it and while searching the net, I found various sources of alarming notes.

This type of shark has been over-fished, and its meat contains a dangerously high level of Methylquecksilber (methyl mercury) as well.
