Finely chop the onion, cut the pumpkin into small cubes. Roast the onion in olive oil, stir briefly and immediately deglaze with the water or stock and the vinegar. Sauté briefly, add the pumpkin pulp, add a little salt, add caraway seeds, crushed garlic, cayenne pepper and tomato paste. Let simmer gently. Halfway through the cooking time, add the paprika. Finish cooking. If the juice goes in, pour in some water or broth again. Add the brunch towards the end of the cooking time. Bring to the boil briefly. If there is too much juice, bind with flour or Maizena.
