Dover Sole is a type of fish that can be found on the coast of Europe. The serving size is around 3 ounces and they are usually served in restaurants. Dover sole is best when it's served with minced shallots or browned butter, lemon juice, peppercorns, and heavy cream. If you want to make Dover Soles for your family at home you should use salt water instead of using freshwater because salt will help with the taste when you cook it, sealing any juices from escaping. Dover sole is also a great substitute for any type of fish that you would like to serve.
