What you will need
This recipe uses 6 simple ingredients that you can find at any grocery store:
- 1.5 cups sour rye starter or store-bought zurek liquid
- 4 cups chicken or vegetable broth
- 2 medium white kielbasa sausages sliced
- 4 large hard-boiled eggs halved
- 3 cloves garlic minced
- 0.5 cup sour cream
Step by step instructions
Step 1: Build the Broth
Pour the broth into a medium saucepan over medium heat and add the minced garlic along with a bay leaf and a few allspice berries. Bring to a gentle simmer and allow the aromatics to infuse for 10 minutes.
Step 2: Add the Rye Starter
Slowly whisk in the sour rye starter or zurek liquid into the simmering broth making sure to add it gradually so it does not curdle. Stir constantly and simmer for another 10 minutes to develop the signature sour flavor.
Step 3: Add the Sausage
Add the sliced white kielbasa to the pot and simmer for 8 to 10 minutes until the sausage is heated through and the flavors have melded beautifully together. Season with salt, white pepper, and marjoram to taste.
Step 4: Finish and Serve
Whisk in the sour cream gradually off the heat to prevent curdling then ladle the soup into bowls. Place two hard-boiled egg halves in each bowl and serve immediately with freshly baked rye bread.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- sour rye starter → a mixture of lemon juice and rye flour dissolved in water as a quick approximation
- white kielbasa → regular smoked kielbasa or bratwurst for a slightly different but still satisfying result
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Adding the sour cream over direct heat which causes it to curdle and creates an unpleasant texture
- Skipping the marjoram which is essential to the authentic flavor profile of traditional zurek
