A hearty and authentic Polish sour rye soup with smoked sausage, featuring a tangy broth made from fermented rye flour and balanced with creamy sour cream and hard-boiled eggs.
Control the sourness by adding the rye starter gradually and tasting often. Brown the sausage well for smoky flavor. Simmer gently after adding the starter to avoid toughening the sausage. Use fresh marjoram or oregano as a substitute. Let the soup rest 10 minutes off heat to settle flavors. For gluten-free, substitute rye starter with fermented vegetable juice or sauerkraut brine and use gluten-free sausage. Vegetarian version omits sausage and uses smoked paprika or liquid smoke.
