Cornichons do a narrower job than standard gherkins, but they often do it better. Their smaller size, firmer bite and sharper profile make them particularly good with cheese, pâté, charcuterie and rich sandwiches where a sweeter pickle can feel too soft or too broad.
This guide keeps the focus on what matters when buying cornichons in the UK: sharpness, crunch, jar format, and whether you want a classic French-style table pickle or a more everyday sandwich option.

Best budget: Opies Cocktail Gherkins in Distilled Malt Vinegar

What separates a good cornichon from an ordinary gherkin?
Before choosing a jar, these are the points worth checking first:
- Size
Smaller pickles usually give the neater, more concentrated bite people expect from cornichons. - Acidity style
Some jars lean clean and sharp; others bring sweetness or a softer malt-vinegar note. - Crunch
Cornichons should stay tight-fleshed and snappy, especially alongside fatty foods. - Jar purpose
Small jars suit occasional cheese-board use; larger jars make more sense for frequent sandwiches or catering. - Extras in the brine
Mustard seeds, onions, dill or spice can add interest, but they also shift the jar away from a plain, classic profile. - Sweetness level
Lower sweetness usually suits charcuterie and pâté better; sweeter jars are easier for general sandwich use. - Availability and substitutions
In UK shops, “cornichons” and “small gherkins” often overlap, so the best substitute is usually based on size and brine style rather than the label alone.
Ranked picks
1) Opies Cornichons & Onions
Best for: most UK shoppers who want a proper table pickle for cheese, cold meats and lunch plates
Opies looks the most convincing all-round option here because the jar format and flavour profile sit close to what many shoppers expect from cornichons: small pickles, sharper presentation, and a more classic accompaniment feel than a burger pickle. The added onions also make the jar more useful for nibbling platters and ploughman’s-style lunches.
Why it stands out
- Small-pickle format gives a more traditional cornichon feel
- Extra onions add variety without needing a second jar on the table
- Better suited to cheese and charcuterie than sweeter sandwich pickles
Main compromise
- The mixed format means it is not a pure cornichon jar, so it may be less ideal if you want only pickles
Works best with
- Cheddar, ham, pâté, terrines, pork pie
- Picnic boards and no-fuss lunch spreads
Practical swap
- If this is unavailable, choose another small gherkin jar with a sharper, less sweet brine rather than a burger slice format
2) Biona Organic Gherkins
Best for: shoppers who want a smaller, cleaner-feeling jar for serving rather than heavy daily use
Biona’s jar looks better positioned for people who want cornichons as an accompaniment rather than as a burger topping. Smaller pickles and a more restrained presentation usually suit richer foods, and this type of jar tends to feel more at home on a cheese board than in a hot dog bun.
What makes it appealing
- Small format is closer to cornichon use than standard sandwich gherkins
- Good fit for grazing boards, salads and cold plates
- Suitable when you want a jar that feels less sweet-led
What to note
- Usually less cost-effective for frequent use than larger or multipack jars
Best use
- Set out whole with cheese and cured meats
- Slice into potato salad or tartare-style sauces when you want extra bite
Practical swap
- Any small organic or continental-style gherkin jar with limited sweetness
3) Sixsigma Foods Cornichons 2kg
Best for: frequent use, catering-style prep, and households that go through pickles quickly
This is the jar for volume rather than delicacy. A 2kg cornichon pack makes sense when the priority is cost per serving, sandwich production or regular entertaining. It is less about gifting or table presentation and more about keeping a dependable stock on hand.
Strong points
- Better value route for high-volume use
- Large jar is practical for sandwich stations, buffets and prep kitchens
- Cornichon format is more useful than slices when you want flexibility
Limitation
- Big jars take up fridge space and make little sense for occasional use
Best use
- Slice for baguettes, deli sandwiches and tuna mayo
- Serve in bowls for grazing platters and buffet spreads
Practical swap
- Large dill gherkin jars can cover a similar role if true cornichons are hard to find, though the flavour will often be broader and less sharp
4) Opies Cocktail Gherkins in Distilled Malt Vinegar
Best for: traditional British pickle lovers who want a cornichon-adjacent option
This is not the strictest cornichon jar in the group, but it is a realistic UK buy for shoppers who mainly want small, punchy pickles with familiar cupboard appeal. The malt-vinegar character gives a rounder British profile than a more French-style cornichon, which can actually work better with cheddar and cold meats in many UK households.
Why it earns a place
- Easy bridge between gherkins and cornichons
- Smaller size still gives useful bite and portion control
- Familiar malt-vinegar style pairs well with classic British lunch foods
Trade-off
- Less classic cornichon sharpness than jars geared toward continental-style serving
Best use
- Ploughman’s lunches
- Cheese toasties, pork pies, buffet plates
Practical swap
- Any small malt-vinegar gherkin jar if you prefer British pantry flavour over stricter cornichon character
5) Mrs Elswood Sandwich Gherkins
Best for: shoppers who want an easy all-purpose pickle and are happy to bend the “cornichon” category slightly
Mrs Elswood is more sandwich-friendly than board-friendly, but it deserves a place because many UK shoppers searching for cornichons are really trying to avoid overly sweet, oversized pickles. This jar gives a practical middle ground: widely recognisable, straightforward to use, and more versatile for packed lunches than for formal serving.
Reasons to consider it
- Convenient everyday jar for wraps, sandwiches and burgers
- Easier entry point than some sharper cornichon jars
- Reliable for households that want one pickle jar rather than several niche ones
Drawback
- Less refined and less classic in style than smaller, sharper cornichon options
Best use
- Lunch sandwiches and quick snack plates
- Chopped into mayo-based fillings
Practical swap
- Kühne gherkins or other sweet-and-sour small pickles if you want similar convenience with a slightly more continental feel
6) Melis Pickled Gherkins
Best for: shoppers who want a fuller jar with more everyday versatility than a specialist cornichon
Melis sits in the space between specialist table pickle and general-use gherkin. It is a sensible option if you want enough sharpness for cold platters but still need a jar that can move into sandwiches, wraps and side salads without feeling too niche.
Why some shoppers will prefer it
- More flexible than a very small, very sharp cornichon
- Decent fit for mixed households with different pickle preferences
- Good stepping-stone if you find classic cornichons too intense
Watch-out
- The broader gherkin style can feel less focused if your aim is a classic cornichon with pâté or terrines
Best use
- Mezze-style plates, sandwiches, chopped salads
- Side dish for grilled meats or buffet food
Practical swap
- Any medium-sized pickled gherkin jar with modest sweetness
How to choose by shopper type
For cheese boards and charcuterie
Go smaller and sharper. Cornichon-style jars or small gherkins with limited sweetness work better because they cut through rich foods without taking over the plate.
For sandwiches and packed lunches
A more forgiving jar makes sense. Sandwich gherkins or small sweet-and-sour pickles are easier to use day to day and suit mixed household tastes.
For classic British lunch plates
Malt-vinegar gherkins are often the better fit. They may not be textbook cornichons, but they pair naturally with cheddar, ham and pork pies.
For bulk prep
Choose the biggest jar you can realistically finish. Large-format cornichons are useful, but only if you have the fridge space and use them often enough to justify the format.
Availability and sensible substitutions
Cornichons are available in the UK, but not always in the same volume or variety as standard gherkins. If a true cornichon jar is out of stock, the most useful substitution is usually:
- small gherkins instead of large ones
- less sweet brine instead of burger-style sweetness
- whole pickles instead of slices
That substitution keeps the texture and serving style closer to what cornichons are meant to do.
FAQs
Are cornichons different from gherkins?
Usually, yes in style rather than species. In UK shopping terms, cornichons are generally smaller, sharper and more geared toward serving with cheese, pâté and charcuterie.
Which cornichons are best for a cheese board?
Smaller, less sweet jars tend to work best because they cut through richness cleanly.
Are sandwich gherkins the same as cornichons?
Not really. Sandwich gherkins are often milder and more general-purpose, while cornichons are usually firmer, smaller and sharper.
What should I look for on the label?
Check size, sweetness, vinegar style, and whether the jar is whole, sliced or mixed with extras such as onions or mustard seeds.
Are large jars worth buying?
Yes for regular use, buffet prep or bigger households. For occasional use, a smaller jar is usually the safer buy because texture matters more than headline value.
What goes well with cornichons?
Cheddar, soft cheese, pâté, ham, roast meats, smoked fish, potato salad and deli-style sandwiches.
Conclusion
If you want the closest match to a traditional cornichon role, Opies Cornichons & Onions is the strongest all-round pick from this set. If you want a neater serving jar, Biona Organic Gherkins looks like the better table option. If price per serving matters most, Sixsigma Foods Cornichons 2kg is the practical bulk choice.
