A traditional recipe for the best Polish fermented cucumbers (ogórki kiszone) - small, firm cucumbers naturally lacto-fermented in a simple salt brine with garlic, dill and horseradish. Crisp, tangy and gut-friendly, they keep for months in a cool pantry.
oak, blackcurrant, grapevine or cherry leaves - optional, for extra crunch

Instructions:
Wash the cucumbers thoroughly under cold running water. Rinse the dill, horseradish and any leaves. Cut the horseradish root into strips and separate the garlic into cloves - there is no need to peel them.
Prepare 4 clean 1-litre jars and their lids, ideally sterilised with boiling water. Use only undamaged jars and lids.
Divide all the ingredients into four equal portions. Into the bottom of each jar put some dill, garlic cloves, horseradish pieces and a leaf or two (if using). Pack the cucumbers in vertically and as tightly as you can, then lay a few of the smallest cucumbers flat across the top.
Make the brine: bring 2 litres of water to the boil and stir in 4 level tablespoons of rock salt until it fully dissolves.
Pour the hot brine into the jars, about 500 ml per 1-litre jar, covering the cucumbers completely. Shake each jar gently to release any trapped air bubbles, then seal tightly.
Leave the jars at room temperature (around 20°C/68°F) for 3 days, then move them to a cool pantry or cellar. The cucumbers will be ready to eat after about 2 weeks, and no later than 20 days.
Notes:
For firm, crunchy pickles, always add a piece of horseradish root - oak, blackcurrant, grapevine or cherry leaves help too.
Choose small, fresh, firm cucumbers with no blemishes. Avoid large, overgrown ones as they turn hollow and soft once fermented.
In the first few days the jars may fizz and a little brine may escape - this is normal, active fermentation. Do not open them; just wipe the outside.
Once fermentation starts, keep the jars somewhere cool so the cucumbers stay firm and do not puff up or go hollow.
Rock (non-iodised) salt is best as it carries the most minerals. The brine also works cold - the pickles turn out just as well.
