Pumpkin Chile Vichyssoise
Sweet pumpkin, smoky chiles, and tangy buttermilk make this a great cold-weather soup. Be creative with substituting other spices (cinnamon, ginger, cloves, cumin, etc.) to change the feel of the soup. It's great hot or cold with a bit of creme fraiche.
If soup is too thick, thin with broth or buttermilk to taste.
