Step 1
Cut pork shoulder into 1.5-inch cubes. Peel and quarter potatoes. Peel and halve onion. Peel carrot and cut into chunks.
Step 2
Hard-boil eggs if not already done. Cool and peel, then halve them.
Step 3
In a large pot, bring water to a boil. Add pork shoulder cubes and ribs, skimming foam as it rises. Simmer for 10 minutes.
Step 4
Add halved onion, carrot chunks, minced garlic, bay leaves, marjoram, and caraway seeds. Simmer for 40 minutes until pork is tender.
Step 5
Add potatoes and salt. Simmer for 15 minutes until potatoes are nearly tender.
Step 6
Slowly stir in rye sourdough starter to avoid lumping. Simmer for 5 minutes until potatoes are fully cooked.
Step 7
Season with salt and black pepper to taste. Adjust sourness by adding more żur if desired.
Step 8
Ladle soup into bowls. Top each with a hard-boiled egg half and fresh dill. Serve with thick slices of rye bread.
