In a soup pot fry the bacon until done. Add the onions and cook until lightly caramelized, 5-7 minutes. Add the garlic and cook another minute. Stir in the tomato paste and spices and cook another minute. Add the chicken broth and sauerkraut and bring to a boil. Reduce the heat to medium and simmer, covered, for 20 minutes. Stir in the crème fraîche or sour cream and heat through (do not boil).
Serve hot with a dollop of crème fraîche or sour cream. Crusty bread and a leafy green salad make great accompaniments.
