Currywurst
Sliced fried sausage doused in a curry-spiced ketchup sauce, dusted with more curry powder and served with fries.

Where it comes from
Usually traced to a postwar Berlin vendor who mixed ketchup with curry powder obtained from British soldiers when spices were scarce, though the exact circumstances are contested and several people have claimed credit.
What cooks argue about
Whether the sausage keeps its skin on or gets peeled before slicing is a real regional split, changing the bite from a snap to soft throughout, and the sauce ranges from quick to slow-simmered.
Versions
Nobody has published a currywurst here yet. When somebody cooks one from a video and publishes it, their version appears in this list, with a link back to the original.
