Cut the sausage and onions into small cubes. Heat the butter in a saucepan, add the flour, and stir until lightly browned. Slowly add the water, stirring constantly to avoid lumps. Bring to a boil briefly, then add the sausage and onion cubes, followed by the tomato paste. If you like, you can first fry the sausage and onion cubes briefly in a separate pan or sauté them until translucent. Mix everything well, add the vinegar and sugar, and season with salt and pepper. It goes well with pasta. I remember this sauce from my mother, who worked as a cook in a holiday camp in the former GDR.
