Lightly Salted Cucumbers: How Much Salt, Brine and How Long They Take
Lightly salted cucumbers are the classic summer snack: ready in a night or two, with no sterilising or canning. The whole secret comes down to three things – the strength of the brine, the temperature and the time. Below we cover how much salt to use, which brine to choose (hot or cold), how long the cucumbers take and why they sometimes turn out soft.
In short: for 1 litre of water use 2 tablespoons of salt, slightly heaped (≈50–60 g). Pour over hot brine and they are ready overnight (8–12 hours); cold brine takes about a day. For crunch you need firm pickling cucumbers, cold water and a leaf of horseradish, oak or blackcurrant. Keep them in the fridge, otherwise lightly salted cucumbers quickly turn into fully salted ones.
How much salt for lightly salted cucumbers
The key is the salt-to-water ratio. Too little and the cucumbers go sour and soft; too much and they are over-salted. Universal proportions:
| For | Salt | When to use |
|---|---|---|
| 1 litre water (brine) | 2 tbsp, heaped (≈50–60 g) | classic, in a jar or pot |
| 1 kg cucumbers (dry salting) | 1 tbsp (≈25–30 g) | in a bag, no water |
| 1 litre sparkling water | 2 tbsp, heaped | mineral-water method, faster |
Use plain rock salt, not iodised or extra-fine: iodine makes the brine cloudy and softens the cucumbers. Sugar is optional, but a pinch lifts the flavour.
Hot brine or cold – which to choose
| Brine | Ready in | Texture | Best for |
|---|---|---|---|
| Hot (boiling water) | 8–12 h | softer, brighter flavour | when you need it fast |
| Cold (filtered water) | ≈24 h | maximum crunch | when you have time |
Want both fast and crisp – pour over hot brine, let it cool on the counter for 1–2 hours, then move to the fridge: the cucumbers salt by morning and stay firm.
How long lightly salted cucumbers take
- Hot brine – 8–12 hours (set them in the evening, ready by morning).
- Cold brine – about a day.
- Express in a bag (sliced into rounds or sticks, dry salting) – 2–3 hours.
- Whole cucumbers take longer than cut ones. To speed things up – trim the ends or prick them with a fork.
Methods: jar, pot, bag
The method mainly affects speed and convenience; the flavour comes from the brine and the spices:
- In a jar or pot with brine – the classic way: pack the cucumbers with garlic and dill and pour over hot or cold brine.
- Dry salting, no water – the cucumbers release their own juice. 👉 Crispy lightly salted cucumbers, dry salting
- In a bag – the fastest method, for cut cucumbers. 👉 Lightly salted cucumbers in a bag with garlic
- In mineral water – the fizz speeds up salting and adds crunch. 👉 Lightly salted cucumbers in mineral water
How to keep them crunchy
- Choose pickling varieties with bumps, firm and small – smooth salad cucumbers go soft.
- Soak the cucumbers in cold water for 2–4 hours – they firm up.
- Add a leaf of horseradish, oak, blackcurrant or cherry – the tannins keep them crisp.
- Use cold water and don't leave them in a warm spot.
- Don't over-hold them – move them to the cold in time.
Common mistakes
- Too little salt – the cucumbers go sour and soft.
- A warm place – they over-ferment in a day; keep them cool.
- Salad varieties (long, smooth) – no crunch.
- Iodised salt – cloudy brine and softening.
- Over-holding – lightly salted turn into fully salted.
How to season
The basic set: garlic, dill umbrellas, a horseradish leaf and black peppercorns. For aroma and crunch add a blackcurrant or cherry leaf; for heat, a piece of chilli. Lightly crush the garlic and herbs so they release their aroma faster.
How long lightly salted cucumbers keep
In the fridge lightly salted cucumbers are at their best for 3–5 days: after that they keep salting and turn fully salted and more sour. To slow this down – pour off some of the brine or move the cucumbers into clean cold water. Don't keep them warm: they over-ferment within a day.
❓ Frequently asked questions
How much salt per litre of water for lightly salted cucumbers?
Two tablespoons of salt, slightly heaped (about 50–60 g) per litre of water. Use plain rock salt, not iodised.
How long do lightly salted cucumbers take?
In hot brine – overnight (8–12 hours), in cold brine – about a day, sliced in a bag – 2–3 hours.
Why do lightly salted cucumbers turn out soft?
Usually because of a warm place, salad varieties, too little salt or iodised salt. Cold water, firm pickling cucumbers and a leaf of horseradish or oak help.
Can I make them without dill?
Yes. Dill and garlic give the classic aroma, but you can replace them with a horseradish or blackcurrant leaf, or just garlic and pepper.
Do I need to boil the brine?
No. Cold brine gives crunchier cucumbers but salts more slowly; hot brine is faster but the texture is softer. Choose by how much time you have.
