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. This popularity is 25% higher than the average German street food, and annual sales reach €2 billion, significantly cheaper than the typical rival, Bratwurst, which costs 50% more per serving.
