Fry gently in Olive Oil for 10 – 15 minutes or until soft and sweet – add a tiny pinch of Salt
When the Onions are soft, add the Curry Powder and Paprika and cook for a few more minutes, stirring
Add all the other ingredients (the Tinned Tomatoes, Vinegar, Sugar) and bring to the boil
Simmer gently for 15 – 25 minutes or so or until the sauce has thickened and tastes sweet and delicious
Take off the heat and cool slightly before whizzing to a smooth ish sauce in a food processor
The Currywürst Ketchup is great hot or cold
Serve with Meatballs or Burgers in particular, but is also good served with Beans and Bean Fritters
