Steph, I've been trying to find out what "langusten" is and the nearest I've been able to figure is it's related to lobsters ... a form of crustacean. All references seem to be in German but I've been unable to get a literal translation.

One 'English' paragraph was, "Beside Langusten can be prepared also lobsters, emperor garnet (Scampo) and giant shrimps like the Tigerprawns in a fruchtigen Tomatensauce. All kinds of crustacean profit from slow refining by moderate heat. Thus the meat remains tenderly and juicy."

I know that doesn't read well, and don't know if that helps, but it's about the best I could do.
