Currywurst

Sliced grilled pork sausage smothered in ketchup seasoned with curry powder -- invented by Berlin snack bar owner Herta Heuwer in 1949 using ketchup obtained from British soldiers and curry powder from Hamburg -- has become the defining street food of Berlin and an unlikely cultural institution. Germany consumes approximately 800 million currywursts annually, and the Deutsches Currywurst Museum in Berlin, open from 2009 to 2018, attracted 350,000 visitors before closing.
