Potage Parmentier (Potato & Leek Soup) – Julia Child

Posted here for safekeeping. This is the basic recipe with variations, so you can create your own favorite version. I usually make this non-dairy using vegetable stock, which I actually prefer over the dairy version given here. I usually cook my soup for less time than this recipe indicates and it comes out fine.
