Fry the sausages in a little oil or grill until golden brown and cooked through.
In a saucepan, sauté the chopped onion until translucent.
Add tomato paste, stir briefly, then mix in ketchup, curry powder, paprika, honey, vinegar, and Worcestershire sauce.
Let it simmer for 10–15 minutes until thick and glossy. Adjust seasoning as needed.
Slice the sausages into bite-sized pieces and pour the sauce generously over the top.
Dust lightly with extra curry powder before serving.
Serve with Bratkartoffeln, chips, or a fresh roll for the full German street food experience.
