It's National Vichyssoise Day! This holiday celebrates vichyssoise-a delicious thick, French-style soup made from potatoes, cream, chicken stock, leeks, and onions.
Traditionally served chilled, vichyssoise (pronounced "vee shee swahzz") has a French name but was invented in America. It was created in 1917 by a French chef named Louis Diat when he was working at the Ritz-Carlton in New York. He named the dish after "Vichy," a town near to where he grew up.
