This is a classy yet simple soup from France. I have made mussel soup before but this is the best recipe. Make sure you have the freshest mussels!! Serve with a good loaf of crusty bread to soak up all the wonderful broth! To make this into an entrée add 1/2 pound of cooked pasta, such as penne. Add the pasta to the soup just before serving. This is from Mark Bittman.
