Here's a classic French soup that is a snap to prepare and can be enjoyed hot, cold or at room temperature. We caramelized the leeks first to give the soup a more robust flavor. If you prefer soup with a thinner consistency, add up to two more cups of broth. You could also easily make this vegetarian by using vegetable stock instead of the chicken variety. To clean the leeks, remove the outer, tough dark leaves and trim the root end. Split the leeks in half lengthwise and soak them in cold water for 10 to 15 minutes to remove any grit and dirt.
