What is a cornichon?

A cornichon is a type of small pickled cucumber that is typically used as a condiment or garnish. Cornichons are often made from the smaller, sweeter varieties of cucumber, which are pickled in a vinegar and brine solution with herbs and spices. They have a tart and tangy flavor, with a slightly crunchy texture. Cornichons are commonly used in French cuisine, where they are served alongside charcuterie, or in sandwiches and salads. They can also be chopped and added to mayonnaise or mustard to create a flavorful sauce.
