This potato leek soup with the French name, was invented, not in France (or Vichy) but in New York. At the beginning of the 20th century at the fashionable Ritz-Carlton Hotel, the head chef, a Frenchman, added cream to his mother’s leek and potato soup recipe and served it cold, sprinkled with chopped chives. He called it Creme Vichyssoise Glacee, in honor of the town where he was born. I always feel so decadent when I enjoy this cold, creamy soup with its delicate flavors and smooth texture.

2 tablespoons butter
2 medium potatoes
3 cups chicken stock
