This drink comes from the blog Table Matters, which writes:
This is a variation on the Salty Dog and the Greyhound created at Ruby, a cutting-edge cocktail bar in Copenhagen. The name, in fact, refers to a Danish long-distance bus called the Graahundbus, or “Greyhound bus.” The original calls for a dill-based aquavit from a local micro-distiller rather than the usual caraway-based aquavits you find in the United States. However, widely available brands such as Linie, Aalborg or Krogstad work well.
