Today on My Life as a Foodie In the Kitchen we’re making Potato Leek Soup, or (served cold) vichyssoise to the French. Usually served cold in France, it’s a pureed soup of leeks, potatoes, cream, and chicken stock. I like to serve this soup warm, but then you can’t call it vichyssoise. To me, it’s potato leek soup. Not as sexy, and my apologies to the French.
