Pickled Cucumbers in Jars for Winter
Instructions
I prepare the ingredients. Firm prickly-bumped cucumber varieties stay crunchy after pickling — these are pickling-specific cucumbers. Smooth-skinned slicing cucumbers don't work as well. Water must NOT be chlorinated (kills the lactic-acid bacteria) — use bottled or filtered water.
Cucumbers soak in cold water 1 hour, then thoroughly wash.
Cut off both ends of each cucumber.
Wash jar with baking soda; sterilisation isn't needed (this is fermentation, not preservation). Herbs and seasonings (dill, bay leaf, garlic, peppercorns) layer at the bottom. Optional: a piece of hot pepper for kick.
Cucumbers pack tightly on top — don't press by hand, just tap the jar on a soft surface (towel) to settle them naturally.
Salt dissolves in water for the brine. Make extra — exact amount varies based on cucumber count, and overflow during fermentation is normal.
Cold brine pours into the jar — must completely cover the cucumbers.
A plate or bowl positions UNDER the jar — fermentation produces overflow that must be collected (don't throw away — it's preserved later). Lid covers loosely (NOT screwed). Jar goes to a dark warm spot (cupboard or counter) for 2-3 days.
After 24 hours, the brine starts clouding and bubbles appear — visible signs of active lactic-acid fermentation.
Foaming intensifies. The brine overflows into the catch-bowl below — this is expected and necessary.
Fermentation length varies (2-3 days at warm temps; up to 5 in cooler rooms). Done indicator: foam stops forming.
Drain the brine into a saucepan (include the overflow from the catch-bowl). This valuable lacto-fermented brine becomes the preserving liquid.
Brine pot heats over medium heat.
Meanwhile, rinse cucumbers and jar under running water, return cucumbers to jar with the same herbs and spices.
Before boiling, foam forms on the brine surface — skim off. Then boil 1 minute.
Immediately while still hot, pour boiling brine over the cucumbers in the jar.
Lid screws on (no need to boil — the hot brine sterilises). Invert jar 5 minutes to sterilise the lid, then return upright. Leave to cool.Pickled cucumbers in jars for winter store at room temperature in a regular kitchen cupboard — keep all winter and beyond. Made without vinegar or lemon acid, with excellent salting flavour. Perfect for vinaigrette, hot pickle soup (rassolnik), or simply with mashed potatoes and meat cutlets.Be sure to try them, enjoy your meal!
Tips
- 1
NON-CHLORINATED WATER IS NON-NEGOTIABLE. Step 1's water requirement is critical chemistry. Chlorinated tap water kills the lactic-acid bacteria that drive fermentation — without these bacteria, no proper fermentation, no proper sour cucumbers. Use bottled mineral water (still, not sparkling), filtered water, or boiled-and-cooled tap water (boiling drives off chlorine). The result without chlorine is dramatically different from with chlorine.

THE OVERFLOW IS DESIGNED, NOT A BUG. Step 8's catch-bowl positioning is part of the recipe, not an inconvenience. Active fermentation generates carbon dioxide gas that pushes brine out of the jar — overflow is the visible sign of healthy fermentation. Don't try to prevent it by sealing the jar tight (the jar might explode from pressure). The overflow IS the fermentation working. The captured overflow gets boiled-and-returned later.

THE BRINE-BOIL-AND-RETURN IS WHAT MAKES IT SHELF-STABLE. Steps 12-16's drain-boil-return technique converts the active fermentation into shelf-stable preservation. The boil kills any remaining active bacteria and yeasts; pouring back hot creates a heat-seal-style preservation. Without this step, the cucumbers stay actively fermenting in the jar — fine for fridge storage but not for shelf storage. The recipe explicitly delivers shelf storage; the boil step is essential for that goal.

THE SALTING-HERB OPTIONS. Beyond the recipe's basic dill-bay-garlic-pepper, the Russian-Slavic tradition welcomes additions. Best add-ins: 1 horseradish leaf per jar (gives crunchier cucumbers — natural enzymes), 1-2 blackcurrant leaves (aromatic, traditional), 1 cherry leaf (gives slight cherry aroma), 1 oak leaf (preserves crunch via tannins). Mix any 2-3 of these for variety. The classic Russian "fully-loaded" version includes all available leaves.

FAQ
Pickled vs salted vs lacto-fermented cucumbers — what's the difference? +
Confusing terminology. "Pickled" (English) usually means vinegar-preserved. "Salted" (English) is generic. The Russian "kvashenye" specifically means lacto-fermented (this recipe). Russian "marinovannye" = vinegar-preserved. Russian "solenye" = salted (no vinegar, but may or may not be fermented). This recipe is "kvashenye" — fully fermented in salt brine, no vinegar. The English title "Pickled cucumbers in jars" is slightly imprecise; "Lacto-fermented cucumbers" would be more accurate. Tradition-wise, this is the oldest preservation method, predating vinegar use by centuries.
How long does the preserve keep? +
Properly sealed jars at room temperature in a dark cupboard keep 12+ months. Cool basement extends to 18 months. Once opened, transfer to fridge and use within 2-3 weeks. The cucumbers stay crisp for the first 6 months, soften gradually after. The flavour deepens over months — many connoisseurs prefer 3-6 month aged cucumbers over fresh-fermented. If you spot mould (rare with proper boil step), bulging lids, or off-smells, discard the jar.
Why does my brine sometimes get cloudy or scummy on top? +
Cloudiness during fermentation is healthy — it's the visible presence of lactic-acid bacteria. White scum on top during fermentation is also normal — it's "kahm yeast" (a wild yeast not harmful but produces a slightly off taste if left). Skim it off if it appears. Pink, black, or fuzzy mould (different from kahm yeast) is a problem — discard the batch. The post-boil shelf-stored brine should be clear; if it goes cloudy in storage, that's a sign of incomplete boil and the jar should be discarded.
Can I do this in a non-glass container? +
Traditional Russian fermentation used wooden barrels (best results, hard to source today) or large clay crocks (good results, expensive). Modern glass jars work fine for small batches. Avoid: plastic containers (absorb fermentation odours and may leach chemicals), metal containers (react with the lactic acid). Stainless steel works for the brine-boil step but not for the fermentation itself. Glass jars are the practical modern choice for home cooks.
