What it is
A standard pickling brine is roughly half vinegar and half water with a couple of tablespoons of salt per litre, a ratio that has barely changed in a hundred years because it reliably stops spoilage in its tracks.
Pickling vegetables is the practice of preserving them in an acidic liquid, usually vinegar-based, often with salt, sugar, and spices added for flavour. Quick pickles, sometimes called refrigerator pickles, skip fermentation entirely; you simply pour hot brine over prepared vegetables and chill them, ready to eat within hours. This is different from fermented pickles, which sour through bacteria over weeks rather than through added acid.
The appeal is speed and certainty. Where fermentation asks you to trust time and bacteria, quick pickling gives a predictable result the same day. Cucumbers, carrots, red onions, radishes, and green beans all take well to it, and the high acidity, below pH 4.6, keeps them safe in the fridge for weeks. Most people start with red onions, which turn brilliant pink within an hour and transform a sandwich. A jar costs under €1 in vegetables and replaces shop versions that run €3 or more, often loaded with far more sugar than a homemade batch needs.
How it works
The base recipe is simple: equal parts water and vinegar, salt, and whatever aromatics you like. The decision that matters is which pickle you want. A quick refrigerator pickle uses a higher vinegar ratio and lives in the fridge, ready in 24 hours and crisp for a few weeks. A shelf-stable canned pickle needs a tested recipe and proper processing.
For a basic quick brine, bring 250ml water, 250ml white or cider vinegar of at least 5% acidity, two tablespoons of salt, and a tablespoon of sugar to a simmer until dissolved. The 5% acidity figure matters because weaker vinegar will not preserve safely. Pack your vegetables tight into clean jars with garlic, dill, peppercorns, or mustard seed, then pour the hot brine over to cover completely.
Cut everything to a uniform size so it pickles evenly. Cucumber spears, carrot batons, and cauliflower florets all work. A grape leaf or a pinch of tannin-rich black tea in each jar keeps cucumbers crunchy by slowing the enzyme that softens them.
Let the jars cool, then refrigerate. Flavour deepens over three to five days, so they taste far better at the end of the week than the day you make them.

FAQs
Speed and method. Quick pickles use hot vinegar brine poured over vegetables and are ready in hours, keeping their sharp tang in the fridge for weeks. Fermented pickles use a salt brine and live bacteria over days, developing a deeper sour-funky flavour and natural fizz. For a first go, quick pickling is faster, more reliable, and almost impossible to get wrong.
For quick pickles, equal parts vinegar and water, plus 1 tablespoon of salt and 1 tablespoon of sugar per 500ml of liquid. Use vinegar with at least 5% acidity (standard white, cider, or white wine vinegar). The sugar isn't for sweetness so much as balance, and you can scale it down. Pour the brine hot over the packed jar and let it cool before refrigerating.
Usually heat or old vegetables. Boiling the vegetables instead of just the brine cooks them limp, so pour hot brine over raw veg rather than simmering them in it. A grape leaf, a piece of horseradish, or a pinch of calcium chloride (Pickle Crisp) adds tannins that keep them crunchy. Fresh, firm produce matters more than anything else here.
For quick fridge pickles, a hot soapy wash and thorough rinse is enough, since they live in the fridge and get eaten within weeks. Proper sterilising only becomes essential for shelf-stable canned pickles stored at room temperature, which is a different and more careful process. Clean jars and clean hands cover you for the fridge version.
