Pickling Cucumbers: Cornichons, Pickles & Spiced Gherkins

Pickled cucumbers are a pantry classic – crisp, tangy, and versatile. Whether as a side for a slice of bread, in a salad, or with grilled food: homemade pickles are unbeatable. This article shows you the most important methods and recipe variations – from the quick vinegar pickle to the traditional lacto-fermented cucumber.

Which Cucumber to Use?

Not every cucumber is suited to pickling. Slicing cucumbers are too watery and turn mushy when pickled. You need:

Pickling cucumbers

• Shorter, thicker-skinned varieties (e.g. 'Delikateß', 'National', 'Vorgebirgstrauben')
• Firm, crisp texture holds up well during pickling
• Best harvested at 5–8 cm long (cornichons) or 8–12 cm (dill pickles)

Freshness is key: Ideally pickle cucumbers the same day you harvest them, or the day after. The longer they sit, the softer they get.

The Three Classic Methods

1. Vinegar Brine (Quick & Shelf-Stable)

The best-known method. The cucumbers are pickled in a vinegar-water-sugar-salt brine and processed.

Basic recipe for about 4 jars of 500 ml:

Ingredients:

• 1.5 kg pickling cucumbers
• 500 ml white wine vinegar (6% acidity)
• 500 ml water
• 2 tbsp salt (canning or table salt)
• 3 tbsp sugar
• Per jar: 1 tsp mustard seeds, 1–2 dill stems, 2–3 peppercorns, 1 garlic clove, optionally a bay leaf

Preparation:

1. Wash the cucumbers well, trim the ends (helps the brine soak in)
2. Jars and lids: clean them in the dishwasher or place them in boiling water for at least 5 minutes (BZfE)
3. Put the spices and dill into the jars
4. Pack the cucumbers in tightly
5. Bring the brine to a boil: heat vinegar, water, salt, and sugar until everything is dissolved
6. Pour the hot brine over the cucumbers – leave at least 1 cm of headspace
7. Seal immediately
8. Process in a boiling water bath (time from when it boils). For pickled cucumbers, the NCHFP (Quick Fresh-Pack Dill Pickles, 5% vinegar) gives, up to 1,000 ft: pints 10 minutes, quarts 15 minutes – so 15 minutes for the 500 ml jars here, as they are larger than a US pint. Do not reduce the vinegar in the recipe.

Shelf life: once processed, three to twelve months according to the BZfE, stored cool and dark

2. Lacto-Fermented Pickles (Cloudy, Naturally Fermented)

The traditional method – no heat, no added acid, but fermentation by lactic acid bacteria. These pickles stay raw and alive and have a completely different flavor from vinegar pickles.

Basic recipe:

Ingredients:

• 1 kg pickling cucumbers
• 1 liter water
• 30 g salt (according to the NCHFP, iodized and non-iodized salt both work; anti-caking agents can cloud the brine)
• Dill (flower heads are ideal)
• A horseradish leaf (its tannins prevent softening)
• Garlic, mustard seeds, black pepper

Preparation:

1. Brine: dissolve the salt in cold water (do not boil)
2. Wash the cucumbers, trim off the stem end (it contains enzymes that cause softening)
3. Line the jar/vessel with the spices and herbs
4. Layer in the cucumbers – finish with the horseradish leaf
5. Fill up with the cold brine, all cucumbers must be submerged
6. Weigh down with a weight (cucumbers must not float above the brine)
7. Let ferment: according to the NCHFP about 3–4 weeks at 21–24 °C (70–75 °F), 5–6 weeks at 13–18 °C (55–65 °F); above 27 °C (80 °F) the pickles turn too soft. Check several times a week and remove surface scum or mould promptly. If the pickles become soft, slimy or smell unpleasant: throw them away (NCHFP)
8. Move to a cool spot (fridge or cellar)

Signs of good fermentation: cloudy brine, a slight fizz, small bubbles – that's exactly what you want!

Shelf life: 4–6 weeks in the fridge; use up promptly once opened

3. Quick Pickles (No Canning Required)

If you're short on time: quick pickles are ready within 24 hours and keep in the fridge for one to two weeks according to the BZfE. Not suited for long-term storage, but ideal for small batches.

Ingredients for 1 jar:

• 500 g pickling cucumbers (sliced or cut into sticks)
• 200 ml apple cider vinegar
• 200 ml water
• 1 tsp salt
• 2 tsp sugar
• Spices of your choice

Preparation:

1. Briefly bring the brine to a boil, let cool
2. Put the cucumbers in a clean jar, pour the brine over them
3. Chill – ready after 12–24 hours

Cornichons: The Small and Delicate Kind

Cornichons are miniature pickled cucumbers harvested at no more than 5–6 cm long. They need a special cucumber variety ('Cornichon de Paris', 'Petit Vert de Paris').

What's different in preparation:

• Pickle them immediately after harvesting
• Rub with salt and let sit for 1–2 hours, then rinse (draws out water for extra crunch)
• Classic French brine: white wine vinegar, tarragon, pearl onions, peppercorns

Spice Ideas: Endless Variations

The basic recipe can be varied to taste:

Common Mistakes and How to Avoid Them

Cucumbers turn soft

• Cucumbers were harvested too ripe (too large)
• Stem end wasn't trimmed off (enzymes)
• Not enough tannins → add a horseradish leaf, grape leaf, or oak leaf to the jar

Brine is cloudy (with vinegar pickles)

• Not a good sign in processed vinegar pickles: cloudiness, mould or an odd smell = throw them out
• Cloudy brine belongs to lacto-fermented pickles (see above); anti-caking agents in salt can also cloud it (NCHFP)

Cucumbers taste too sour

• Reduce the vinegar or increase the sugar
• White wine vinegar instead of spirit vinegar = milder

Storage & Shelf Life

According to the BZfE, processed vinegar pickles keep for three to twelve months stored cool and dark. When opening: the brine should be clear and smell typically sour. Cloudiness, mold, or an odd smell = when in doubt, throw it out.

Tip: Always write the canning date on the jar. And: keep opened jars in the fridge and, according to the BZfE, use them up within a few days if possible.

Conclusion

Pickled cucumbers are a perfect beginner project for home canning: simple, quick, and with an immediately visible result. A row of homemade cucumber jars in the cellar isn't just practical – it's a great feeling to be able to enjoy the taste of summer all year round.
