Cornichons are sharply vinegar-flavored pickles made with very small cucumbers (usually no larger than your pinkie finger). The method of making them comes from France, where they are traditionally served with heavier hors d'oeuvres such as pate, cured sausages, and cheese. The bright crunch and sour bite of the cornichons perfectly balance the rich taste and texture of those other foods.

Making cornichons is incredibly easy, with one caveat: you won't find small, finger-sized cucumbers at the grocery store in the United States. Cornichons are one of many great reasons to ​grow your own cucumber plants because cucumbers that small are rarely seen in the market.

This recipe is incredibly simple and enables the home gardener with limited gardening space to pickle the cornichons as the cucumbers reach the right size, rather than waiting for a big batch of tiny cucumbers to be available all at once.

How to Make Cornichons

  1. Choose cucumbers no larger than your ring finger (smaller is better).
  2. Wash them and slice a sliver off of the blossom end of each cucumber. There are enzymes at the tip of the blossom end that could result in a mushy pickle if they are not removed. If you aren't sure which end is the blossom end, slice a sliver off of both ends.
  3. Put a thin layer of coarse kosher or other non-iodized salts in the bottom of a bowl (iodized salt can cause the cornichons to turn off colors). Put a layer of your prepared tiny cucumbers on top. Sprinkle more salt over the layer of cucumbers until they are almost buried in it. Put another layer of cucumbers on top. Add salt. Repeat until you've used up all your baby cucumbers, finishing with a layer of salt on top.
  4. Put the bowl of salted cucumbers in the refrigerator for 24 to 48 hours.
  5. Put the cucumbers in a colander or sieve and rinse the salt off of them. Transfer them to a clean glass jar (it is not necessary to sterilize the jar for this recipe).
  6. Pour white wine vinegar over the cucumbers, enough to cover. If you prefer, you can dilute 3 parts vinegar with 1 part water and still end up with a sharp-tasting cornichon pickle.
  1. Add the optional baby onions or shallots and black peppercorns if you like.


  • Wait at least a week between adding the last cucumber to fill the jar and eating your cornichons. During that week the flavors will "marry" and mellow.
  • Once the jar is full of vinegar-covered baby cucumbers, it will keep in the refrigerator or another cool place for at least 6 months.
  • If you'd like to seal the jars for storage at room temperature, pour the vinegar out of the jar into a small pot. Bring to a boil. Pour the liquid back over the cucumbers, making sure that the cucumbers are completely immersed but there is still half an inch of headspace between the food and the rims of the jars. Cover with canning lids and process in a boiling water bath for 10 minutes.
