About Traditional French Cornichons
French cornichons represent the pinnacle of pickle perfection. Unlike regular dill pickles, these tiny cucumbers pack an intensely sour punch that cuts through rich foods beautifully. Furthermore, authentic cornichons require specific techniques that I’ve refined through extensive testing.
What Makes This Sour Gherkins (Cornichons) Recipe Unique
This recipe delivers restaurant-quality results using ingredients readily available in American grocery stores. Additionally, I’ve included both refrigerator and canning methods to suit different preservation preferences. The key lies in the salt-curing process, which draws out moisture and creates that distinctive crisp texture.

- Look for firm, unblemished skin
- Fresh tarragon should smell intensely aromatic
- White wine vinegar should be at least 5% acidity

Equipment and Preparation
Necessary Equipment
Essential Tools:
- Large mixing bowl for salt-curing
- Fine-mesh colander for draining
- Clean kitchen towels for drying
- Sterilized pint jars (4-6 jars typically needed)
- Water bath canner (if processing for shelf storage)
DIY Alternatives:
- Use a large pot with rack for water bath processing
- Substitute clean dish towels if you lack kitchen towels
- Any large bowl works for the salt-curing process
Step-by-Step Instructions
Prepare Your Workspace
Start by sterilizing all jars, lids, and rings if you plan to can these pickles. However, refrigerator pickles require only clean equipment. Subsequently, gather all ingredients within arm’s reach—this process moves quickly once you start.
Salt-Cure the Gherkins
Wash your cucumbers thoroughly under cold running water. Next, trim off a 1/16-inch slice from the blossom end while leaving ¼-inch of stem attached. This step prevents the pickles from becoming soft during processing.
Place the prepared gherkins in your large mixing bowl. Then, add the kosher salt and stir vigorously to coat each cucumber completely. The salt draws out excess moisture, which is absolutely essential for achieving that signature crunch that makes French-style cornichons so special.
Transfer the salted gherkins to a colander and let them drain for exactly two hours. During this time, you’ll notice significant moisture being extracted. This technique, borrowed from Julia Child’s approach to vegetable preparation, ensures optimal texture in the final product.
Rinse and Dry
After two hours, rinse the gherkins thoroughly under cold water. Pat them completely dry with clean kitchen towels, removing all excess salt from the surface. They’ve absorbed the perfect amount of salt internally, so external salt would create an overly salty final product.
Pack the Jars
Begin layering your sterilized jars with gherkins, cocktail onions, tarragon stems, bay leaves, peppercorns, and mustard seeds. Pack them snugly but avoid crushing the delicate gherkins. This layering technique ensures even flavor distribution throughout each jar.
Prepare the Brine
Bring the white wine vinegar to a rolling boil in a heavy-bottomed saucepan. Once boiling, immediately pour the hot vinegar over the packed vegetables, leaving ½-inch headspace at the top of each jar. The hot vinegar jump-starts the pickling process and helps maintain crispness.
Final Processing
For Refrigerator Pickles: Allow jars to cool to room temperature before refrigerating. These pickles will be ready to eat in 24 hours and improve over the next week.
For Shelf-Stable Canning: Apply lids and rings, then process in a boiling water bath for 10 minutes. Adjust processing time for altitude according to USDA guidelines. After processing, let jars remain in the canner for five additional minutes to prevent thermal shock.
Remove jars and cool on a clean towel for 24 hours. Check seals, label with date, and store in a cool, dark pantry.
Pro Tips for Perfect Results
Temperature Matters: Hot vinegar creates better texture than cold brine methods. Additionally, the thermal shock helps set the pickle’s final texture.
My Biggest Mistake: During my early attempts, I skipped the salt-curing step to save time. Man, oh man, those pickles turned out mushy and disappointing! The salt-curing process cannot be rushed or eliminated—it’s the foundation of proper texture.
Timing Precision: Thomas Keller emphasizes precise timing in his pickling techniques, and cornichons are no exception. Follow the two-hour salt cure exactly for optimal results.

Classic French Cornichon Pickles FAQs
What can I make with cornichons?
Cornichons excel in tartare sauces, potato salads, and as garnishes for cocktails like dirty martinis. They also enhance sandwich spreads and provide acidic balance in rich stews. Many chefs incorporate them into vinaigrettes for added texture and tang.
What is the difference between a pickle and a cornichon?
Cornichons are specific small French pickles made from tiny gherkin cucumbers, while pickles encompass any preserved vegetable. Cornichons feature a more intense sour flavor and crunchier texture compared to standard dill pickles. Additionally, they’re traditionally seasoned with tarragon and mustard seeds rather than dill.
What are cornichons made of?
Traditional cornichons contain small gherkin cucumbers, white wine vinegar, salt, tarragon, bay leaves, peppercorns, and mustard seeds. Some recipes include small onions for additional flavor complexity. The salt-curing process distinguishes authentic cornichons from simple pickled cucumbers.
What is a substitute for cornichons?
Small dill pickles or capers can substitute for cornichons in recipes, though flavor profiles differ significantly. Alternatively, finely dice regular pickles to approximate the size and acidic function. However, nothing truly replicates cornichons’ unique tarragon-forward flavor and crispy texture.

These traditional French cornichons bring authentic bistro flavors straight to your American kitchen. You know what makes them special? It’s that perfect balance of intense sourness and herbaceous complexity that elevates every bite. Whether you’re hosting a sophisticated dinner party or simply want to upgrade your everyday meals, these classic French cornichon pickles deliver restaurant-quality results.
The salt-curing technique might seem intimidating initially, but trust the process—it’s the secret to achieving that signature crunch that makes cornichons absolutely irresistible. Furthermore, once you taste homemade versions, store-bought pickles pale in comparison.
