Currywurst is a popular German fast-food dish made of steamed and fried pork sausage, sliced and topped with curry ketchup, a spiced tomato-based sauce. It’s typically served with French fries or a bread roll (Brötchen). 

To prepare, pan-fry boiled pork sausage, like bratwurst or bockwurst, in hot oil until browned. The sausage should be uncured and unsmoked. Serve with curry ketchup, a sprinkle of curry powder, and optional mustard or mayonnaise on the side.
