Method

  1. Hydrate & Prep
    Soak Dried Mushrooms in 200ml boiling water for 20 mins. Meanwhile, dice the Bacon and Onion. Peel the Carrots, Parsley Root, and Celeriac but keep them whole (do not chop). Peel/crush the Garlic.
  2. Build the Base
    In a large pot, fry the bacon until crisp. Add the onion and cook for 10–12 minutes until soft and golden. Add the whole root vegetables, mushroom liquid (plus mushrooms), Bay Leaves, Allspice, and 2.2L Water. Bring to a boil, then cover and simmer on low for 20 minutes.
  3. Poach Sausage & Eggs
    Prick White Sausages and slide them into the simmering broth. Cook gently for 20 minutes.
    - Multitask:     Meanwhile, boil Eggs in a separate pot (9 mins), cool, peel, and halve.
  4. Strain & Slice
    Fish out the sausages, whole root vegetables
    and bay leaves/allspice. Discard the boiled roots (or save for salad). Slice the sausages into rounds and set aside. Ensure the broth, bacon, and mushrooms remain in the pot.
  5. The Sour Hit
    Shake Zakwas vigorously. Pour into the broth along with crushed garlic, Marjoram (rubbed), and Horseradish. Simmer 10 mins to thicken slightly.
  6. Temper the Cream
    In a mug, whisk Sour Cream with a ladle of hot soup (to prevent splitting), then stir back into the pot. Add the sliced sausage back in.
  7. Season & Serve
    Taste and season with Salt and Pepper (bacon varies, so salt last). Serve hot with the hard-boiled eggs and fresh bread.
Chef's Note & Storage
Fridge 3-4 days. The flavour profile improves significantly after 24 hours as the sourness integrates with the smoke. Reheat gently; do not boil aggressively after adding cream.

The Resurrection Soup

If Poland had a liquid soul, it would be Żurek. Traditionally served at Easter to mark the end of Lent, this sour rye soup has transcended its religious roots to become a national obsession and the world’s arguably most effective hangover cure. Its distinctiveness comes from Zakwas—fermented rye flour and water—which delivers a sharp, lactic tang that cuts through the richness of smoked meats. It is not merely a soup; it is a balance of opposites: creamy yet acidic, smoky yet fresh, heavy yet restorative.

CHEF'S SECRET: The "Hartowanie" (Tempering). Never pour cold cream directly into boiling soup—it will split and look curdy. Ladle a cup of hot broth into the cream first, whisk it to equalise the temperature, then pour that mixture back into the pot. Also, do not boil the White Sausage (Biała Kiełbasa) violently; poach it gently to keep the casing snappy and the meat juicy.

❖

The Fermentation Factor

The backbone of this dish is the Zakwas Żytni. While you can buy it in bottles, the quality varies wildly. Good Zakwas should smell like fresh sourdough bread and lemons. Before you pour it into the pot, you must give the bottle a vigorous shake. The flour settles at the bottom, and that sediment is where the thickening power and the deepest sour flavour live. Without the sediment, you're just adding sour water.
