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".
