Potato Leek Soup (Julia Child's) Potage Parmentier

For a more delicately flavored soup, sub in water for the vegetable stock. This may sound blasphemous, but I felt the original recipe was missing a certain spark. A few modern upgrades (amended in the following recipe) were just the trick. The resulting soup is velvety and immensely soothing and would make for an excellent first course for a Julia-themed dinner — or any French meal, for that matter.
