Finely chop the onion. Slice the garlic. Dice the pepper and potatoes. Cut the cabbage into thin strips. Slice the sausages into rounds and set aside.
Heat the olive oil in a large pot and sauté the onion until golden brown. Add the pepper and cook for a few more minutes. Finally, add the garlic, stir well, then remove the pot from the heat and sprinkle in the paprika powder. Mix thoroughly. Add the ground caraway seeds as well, then pour in the water. Season with salt and black pepper. Bring to a boil.
Once boiling, add the diced potatoes and shredded cabbage. Add a little more salt if needed.
Cook until the vegetables are tender.
In a mixing bowl, combine the sour cream with 3–4 ladles of the hot soup broth and stir until smooth. Pour the mixture back into the soup and bring it to a gentle boil again.
Finally, add the sliced sausages. They only need a few minutes in the hot soup to heat through and become tender.
Serve with a generous spoonful of sour cream on top!
