Cornichons are small, tart pickles made from immature cucumbers called gherkins, typically about one to two inches long. They have a distinctive bumpy skin and are pickled in a vinegar-based brine with herbs and spices such as tarragon, peppercorns, and sometimes pearl onions, giving them a unique tangy and mildly sour flavor. Cornichons are crunchy and less sour than regular pickles, making them a popular condiment, especially paired with rich, savory foods like charcuterie, pâtés, and cheese plates. They are a classic French delicacy often used as a garnish or accompaniment rather than a large side pickle.
