I found the basis for this soup on another website but didn't have all the ingredients called for so I adapted it to suit my less gourmet pantry. I was pleasantly surprised when my non-gourmet pantry turned out this gourmet quality soup! This soup is perfect for an autumn or winter day. I use it as a 1st course for Thanksgiving dinner. It is a savory, slightly sweet soup that will give you a new appreciation for the American chestnut.
