Many years ago I had a bowl of delicious tortellini soup while visiting Washington Island, a small island off "the Door" in Wisconsin. Years later I created this soup after I had an abundance of Au Jus left after serving italian beef for Christmas. The juice has all the spices needed for ths hearty flavorful soup. It has been a Christmas tradition every year since. I even freeze the aujus leftovers though out the year so I can make this soup each winter! Hope you enjoy this as much as my family!
