Today, November 18, 2013, is National Vichyssoise Day. Vichyssoise is a thick soup made of puréed leeks, onions, potatoes,cream, and chicken stock. It is traditionally served cold but can be eaten hot. The origins of Vichyssoise are a subject of debate among culinary historians; Julia Child calls it "an American invention", whereas others observe that "the origin of the soup is questionable in whether it's genuinely French or an American creation". This got lost in another post.
