Kiszone vs Małosolne
Polish fermented cucumbers fall into two categories that are often confused:
- Ogórki kiszone — fully fermented cucumbers, typically sour. Fermentation lasts from one to several weeks depending on temperature and brine strength. These are what most people mean when they refer to Polish pickles.
- Ogórki małosolne — literally "lightly salted". These are cucumbers that have been fermenting for only a few days. They are milder, crunchier, and still slightly sweet. They do not keep as long as fully fermented kiszone.
The preparation method is identical for both. The only difference is the length of fermentation before consumption.
Choosing the Right Cucumbers
Not all cucumbers ferment equally well. The best results come from small to medium-sized cucumbers with thin skin and a firm texture — varieties bred specifically for pickling. The large, smooth-skinned greenhouse cucumbers sold for fresh eating are unsuitable: their high water content and soft skin produce a mushy result within days.
In Poland, pickling cucumbers are available in markets from July through August. They are typically sold by weight in quantities starting at one kilogram. Cucumbers should be as fresh as possible — ideally fermented within 24 hours of harvest. Older cucumbers tend to produce hollow pickles.
Practical note: If the blossom end of the cucumber (the end opposite the stem) contains a small white spot, cut a thin slice off that end before packing. This end contains enzymes that can soften the texture during fermentation.
The Brine
The brine for ogórki kiszone is made by dissolving salt in cold or room-temperature water. The standard concentration in Polish recipes is between 1 tablespoon and 1.5 tablespoons of non-iodised salt per litre of water, which corresponds to approximately 15–20 grams of salt per litre.
| Water volume | Salt at 15 g/L | Salt at 20 g/L |
|---|---|---|
| 1 litre | 15 g (~1 tbsp) | 20 g (~1.3 tbsp) |
| 2 litres | 30 g | 40 g |
| 3 litres | 45 g | 60 g |
Higher salt concentrations slow fermentation and produce a firmer, less sour pickle. Lower concentrations speed fermentation but produce a softer texture and a more acidic flavour in less time. Most Polish recipes sit in the middle of this range.
Aromatics
The aromatic combination in ogórki kiszone is one of the most regionally specific aspects of the recipe. Common additions include:
- Fresh dill with seed heads — the most essential flavouring. Use mature dill with developed seed heads if possible, not young leaf dill.
- Garlic cloves — 3–5 cloves per litre jar, peeled and lightly crushed.
- Horseradish — a piece of fresh horseradish root (approximately 5 cm per litre jar). This is traditional and also helps maintain firmness.
- Oak leaves, cherry leaves, or blackcurrant leaves — contain tannins that help keep cucumbers crisp. Used in many older recipes; less common today.
- Black peppercorns and allspice — optional, added for flavour complexity.
- Hot chilli pepper — regional addition, particularly in some southern Polish recipes.
Packing and Fermentation
- Clean the jar or crock thoroughly with hot water.
- Place a layer of dill, garlic, and horseradish at the bottom of the vessel.
- Pack cucumbers vertically and tightly. The tighter the pack, the less the cucumbers shift during fermentation, and the more evenly they ferment.
- Add another layer of aromatics on top of the cucumbers.
- Pour the brine over the cucumbers until they are fully submerged. The brine should cover the cucumbers by at least 1–2 cm.
- Weight or cover to keep cucumbers submerged. A sealed plastic bag filled with brine (not plain water — use brine to avoid dilution if the bag leaks) works well in a wide-mouth jar.
- Cover loosely to allow gas to escape. Do not seal airtight.
- Keep at room temperature, ideally 18–22°C. After 1–3 days, the brine will turn cloudy — this is expected and indicates active fermentation.
Timeline
At room temperature (around 20°C):
- Days 1–2: Brine may begin to show bubbles. No significant sourness yet.
- Days 2–4: Ogórki małosolne stage. Light sourness, cucumber is still crisp and slightly sweet. Eat now if you prefer the mild version.
- Days 5–14: Fermentation progresses. Flavour becomes progressively more sour. Texture softens slightly.
- Weeks 2–4: Fully fermented ogórki kiszone. Deep sour flavour, distinctive aroma, firm but not crunchy texture.
Storage and Serving
Once the desired level of sourness is reached, move the jar to a cold environment — a refrigerator or cool cellar below 10°C. Fermentation slows significantly. The cucumbers will keep in brine for several months in cold storage, though the texture gradually softens over time.
Ogórki kiszone are eaten on their own, alongside rye bread and cold cuts, as a component of bigos (hunter's stew), or chopped into soups such as rassolnik or Polish pickle soup (zupa ogórkowa). The fermentation brine itself is sometimes consumed as a tonic.
