📝 About This Recipe

Żurek is the crown jewel of Polish comfort food, a deeply aromatic soup characterized by its unique tart flavor derived from fermented rye flour. This centuries-old recipe balances the tang of the 'zakwas' with smoky bacon, savory marjoram, and creamy horseradish, creating a velvety texture that warms the soul. Traditionally served during Easter but beloved year-round, it is a masterful symphony of fermentation and rustic farmhouse flavors.

🥗 Ingredients

The Sour Base (Zakwas)

  • 2 cups Zakwas (Fermented Rye Starter) (homemade or high-quality store-bought)

The Broth and Meats

  • 7 ounces Smoked Bacon (Boczek) (diced into small cubes)
  • 4 pieces White Polish Sausage (Biała Kiełbasa) (raw or parboiled)
  • 10 ounces Smoked Pork Ribs or Ham Hock (for a deep smoky base)
  • 8 cups Water or Vegetable Stock (cold)
  • 1 large Onion (finely chopped)
  • 4 pieces Garlic Cloves (minced)

Vegetables and Aromatics

  • 1 medium Carrot (peeled and left whole)
  • 1 small Parsnip or Parsley Root (peeled and left whole)
  • 2 tablespoons Dried Marjoram (rubbed between palms to release oils)
  • 3 pieces Bay Leaves
  • 5 pieces Allspice Berries
  • 6 pieces Black Peppercorns

Finishing Touches

  • 1/2 cup Heavy Cream (18% or 30%) (tempered)
  • 1 tablespoon Prepared Horseradish (grated, for an extra kick)
  • 3-4 pieces Hard-boiled Eggs (halved or quartered for garnish)
  • to taste Salt and Black Pepper

👨‍🍳 Instructions

  1. 1

    In a large, heavy-bottomed pot over medium heat, add the diced bacon. Sauté until the fat renders out and the bacon becomes crispy and golden brown.

  2. 2

    Add the chopped onions to the bacon fat. Cook for 5-7 minutes until translucent and slightly caramelized.

  3. 3

    Stir in the minced garlic and cook for just 1 minute until fragrant, being careful not to burn it.

  4. 4

    Pour in the water or stock. Add the smoked ribs (or ham hock), the whole carrot, the parsnip, bay leaves, allspice, and peppercorns.

  5. 5

    Place the raw white sausages into the liquid. Bring the pot to a gentle boil, then reduce heat to low and simmer partially covered for 30 minutes.

  6. 6

    After 30 minutes, carefully remove the white sausages and the whole vegetables (carrot/parsnip). Slice the sausages into rounds and set aside. The vegetables can be discarded or diced and returned to the soup if desired.

  7. 7

    Shake your bottle of 'zakwas' (rye starter) well to ensure the flour at the bottom is incorporated. Slowly pour the zakwas into the simmering broth while stirring constantly.

  8. 8

    Continue to simmer the soup for another 10 minutes. You will notice the soup beginning to thicken slightly and take on a beautiful, creamy, opaque appearance.

  9. 9

    Add the dried marjoram by rubbing it between your palms directly over the pot; this friction activates the herb's essential oils.

  10. 10

    Stir in the prepared horseradish. This provides a subtle heat that cuts through the richness of the pork.

  11. 11

    Temper the heavy cream by mixing it with a few ladles of the hot soup in a separate bowl before adding it back into the pot. This prevents the cream from curdling.

  12. 12

    Return the sliced sausages to the pot. Taste the soup and adjust the seasoning with salt and plenty of freshly ground black pepper.

  13. 13

    Simmer for a final 2-3 minutes to ensure everything is heated through. The soup should be tangy, smoky, and deeply savory.

  14. 14

    Serve hot in deep bowls, garnished with halves of hard-boiled eggs and a sprig of fresh parsley if desired.

💡 Chef's Tips

If you cannot find store-bought zakwas, you can make it 5 days in advance by mixing rye flour with water, garlic, and bay leaves in a jar. Always temper your cream with hot broth before adding it to the pot to ensure a perfectly smooth, velvety texture. Don't skip the marjoram; it is the signature herb of this dish and aids in the digestion of the hearty ingredients. If the soup is too sour for your taste, add a pinch of sugar or a bit more cream to balance the acidity. For the most authentic experience, use 'Biała Kiełbasa' (Polish white sausage), which is unsmoked and garlic-forward.

🍽️ Serving Suggestions

Serve inside a hollowed-out loaf of crusty rye bread (Chlebowa Miska) for a stunning presentation. Pair with a glass of chilled Polish vodka or a crisp, cold pilsner beer. Offer extra horseradish on the side for those who prefer a more pungent, spicy kick. Serve with a side of thick-cut, buttered sourdough bread to soak up every drop of the broth.
