Currywurst

Currywurst is a fast food dish of German origin consisting of sausage with curry ketchup. It was invented in 1949 by Herta Heuwer, who began selling it at a food stand in Berlin. The Deutsches Currywurst Museum estimated that 800 million currywursts are eaten every year in Germany, with 70 million in Berlin alone. The invention of currywurst is attributed to Herta Heuwer in Berlin in 1949, after she obtained ketchup, or possibly Worcestershire sauce, and curry powder from British soldiers in Germany. She mixed these ingredients with other spices and poured them over grilled pork sausage. Heuwer started selling them at a stand in Charlottenburg, where it became popular with construction workers rebuilding the devastated city.
