Poland's great winter soup: a golden broth turned bracingly sour with fermented pickle brine

Origin: Warsaw / Kraków, Poland

From the journey of Cucumber.

Zupa ogórkowa is one of Eastern Europe's most distinctive soups and Poland's great winter comfort food: a golden broth of chicken or pork stock, root vegetables, and potato, soured dramatically with the brine from fermented dill pickles (ogórki kiszone) and packed with grated sour pickles that dissolve their sharp, lactic flavour through the entire bowl. Eastern Europe has the world's deepest pickle culture, and Poland is its heartland. Fermented dill cucumbers (made in ceramic crocks every autumn across Polish households and farms, fermenting slowly over weeks with whole dill heads, garlic, horseradish root, bay leaves, and black peppercorns) are a cornerstone of Polish food identity. The distinction between fermented pickles (kiszone, soured with lactic acid) and vinegar pickles (konserwowe, preserved with acetic acid) is fundamental and cannot be glossed over: only lacto-fermented pickle brine has the right sharp, slightly funky, complex sourness that gives zupa ogórkowa its character. Vinegar pickles will produce a harsher, flatter result. The brine from the pickle jar is never wasted in a Polish household; it goes into soups, marinades, vodka chasers, and the traditional hangover cure (the lactic acid and electrolytes replace what was depleted). Zupa ogórkowa is beloved as a winter restorative and as a hangover remedy with near-mythic status in Polish culture. The soup should taste noticeably, proudly sour; if you are uncertain whether you have added enough pickle brine, the answer is no.

Ingredients

Base

1.5 litres good chicken or pork stock (homemade is ideal, this is a dish that rewards a proper stock)

Pickles

4 lacto-fermented dill pickles (ogórki kiszone), NOT vinegar pickles; about 300g
200 ml pickle brine from the jar, save all of it; you may want more

Vegetables

3 medium potatoes, peeled and cut into small 1.5cm cubes
2 medium carrots, peeled and cut into small dice or thin half-rounds
1 parsnip, peeled and cut into small dice
1 medium onion, finely diced

Aromatics

2 cloves garlic, thinly sliced
2 tbsp unsalted butter
2 bay leaves
4 black peppercorns, whole

Thickening

2 tbsp plain flour

Enrichment

3 tbsp sour cream (śmietana), plus extra to serve

Finish

4 sprigs fresh dill, fronds only, roughly chopped

Seasoning

0.5 tsp fine salt, to taste, add only at the end; the brine is already very salty

Method

In a large saucepan, melt the butter over medium heat. Add the onion and cook for 5–6 minutes until softened and translucent. Add the garlic and cook for 1 minute more. Sprinkle over the flour and stir for 1 minute to cook out the raw flour taste.
Pour in the stock gradually, stirring to incorporate the roux smoothly. Add the bay leaves and peppercorns. Add the carrots and parsnip. Bring to a gentle boil, then reduce to a simmer and cook for 10 minutes.
Add the potato cubes and continue simmering for 15–20 minutes until all the vegetables are completely tender.
While the soup cooks, coarsely grate the pickles on a box grater. Do not squeeze them; retain all their juice. Set aside.
When the vegetables are tender, add the grated pickles and 150ml of the pickle brine to the soup. Stir and simmer for 5 minutes. Taste. The soup should now be noticeably sour. Add more brine to taste; most people who make this dish for the first time do not add enough. Season with salt only if needed (the brine will have added considerable salt).
Remove from heat. In a small bowl, loosen the sour cream with a ladle of hot soup, whisking to temper it. Stir the tempered sour cream back into the soup: this prevents curdling.
Serve immediately in deep bowls, scattered with fresh dill. Put the sour cream on the table for people to add more. Have the remaining pickle brine available for any guest who wants to sour their bowl further.

Notes

The single most important ingredient in this recipe is the quality of the pickle: they must be lacto-fermented (kiszone), not vinegar-preserved (konserwowe). Look for them at Polish delicatessens, Eastern European grocery stores, or good farmers' markets. The brine from these jars is equally important; bottle it and refrigerate, as it keeps for months and has many uses. The soup keeps for 2–3 days refrigerated but becomes progressively more sour as the pickle brine continues to work. This is not a flaw. For a richer version, add 150g of smoked Polish sausage (kiełbasa wędzona), sliced and fried until coloured, added in the final step.
