A puck of sour-milk cheese marinated in onion vinaigrette, eaten with dark bread and butter in Frankfurt's apfelwein taverns. The Musik, the music, is the onions, and what they do to you later.

Handkäs is a hand-formed sour-milk cheese from the Hessen countryside, low in fat and high in pungency. Sachsenhausen's taverns made it their standard apfelwein companion by the 19th century, marinating the cheese in vinegar, oil and raw onions, the mixture locals call Musik. Tradition says you eat it with a knife on bread, never a fork, and the caraway on top is a dividing line between families. It survives because it does one job perfectly: it makes the next Schoppen of sharp cider taste sweeter than the last.
