A very elegant soup that is made with your leftover Christmas turkey. It takes awhile, but you will thank yourself later if you freeze this soup to enjoy for months to come!
If desired, add 2 tablespoons of dry sherry to each bowl before serving. An additional carrot and two additional celery stalks may be diced and added with the mushrooms, if desired. Soup will gel if kept refrigerated but will thin when reheated.
