No cheese or charcuterie plate is complete without cornichons for me; I must have these tart, pickled French gherkins with them. I love them with a Ploughman’s lunch, and they are a traditional accompaniment to raclette. But I started wondering; are cornichons just pickled baby cucumbers, or are they a specific kind of cucumber that grows very small? Cornichons are about the size of your pinky finger, about an inch and half in length and less than a quarter inch in diameter.
