Goujon is the French word for small, fried strips of fish, and apparently sole is the most popular catch for this preparation.
Cornichon is also a French word, but is in a little more common usage among English speakers. Cornichons are pickled gherkin cucumbers. In France, these tart pickles are classically served with pâtés and smoked meats. In other countries, they are apparently served with small, fried strips of fish.
