I had such a delicious soup a few weeks ago. It can be pretty socially fluid around here, with so many students in Boston who come and go at various times during the year. Some friends got together for dinner before a few were leaving town for the summer, and Dan Nystedt cooked up a fantastic dinner for us ... including this soup. Usually pureed soups don't do much for me, but this one was so flavorful and had this little spicy kick to it. Awesome. So here it is.
