Wrinkles, which are pickled whelks, are an old Maine delicacy in the Downeast region. The seafood snack was little known to the general public until 2002, when Terrie Pinkham and her daughter, Wanda, launched DownEast Whelks. Since then, the pickled sea snails with the funny name have inspired curiosity among the uninitiated and delighted those who have rediscovered the culinary treats they once savored.
