Other forms: cornichons
A cornichon is a tart, crunchy little pickle. You can eat cornichons on their own, or chop them up and add them to your tuna or egg salad.
In the U.K., people call these tiny pickles gherkins, but in France and the U.S., they're cornichons. Traditionally, cornichons are very small cucumbers pickled in vinegar and flavored with tarragon. They're tart, but much less sour and salty than dill pickles. The French cornichon literally means "little horn," from the Latin cornu, "animal horn."
