I have made this soup recipe every Thanksgiving (and usually Christmas too) for as long as I can remember. It is really, really good.
If you don’t want to go through the work of roasting and shelling chestnuts (an it can be pretty tedious) Williams-Sonoma (for one place) sells them in jars pre-peeled. I just bought two today for $15 each on sale.
Did I mention how good this soup is?
