Vichyssoise

This thick French soup is made with puréed leeks, onions, potatoes, cream, and chicken stock. There is an ongoing debate about its origin – some claim it has French roots, while others insist that the soup is an American invention.

One group of food historians say that the soup was invented by French chef Jules Gouffe in 1859, while others believe the original creator to be Louis Diat, a French chef who worked at the New York Ritz-Carlton. Inspired by the potato and leek soup of his childhood, he named the soup crème Vichyssoise glacée after his hometown of Vichy.
