The main difference between vichyssoise and potato-leek soup is the temperature at which each is served. Potato-leek soup is usually served hot, while vichyssoise is served cold, making the latter a nice, chilled offering during the summer months.
Because classic vichyssoise is a creamy golden beige color, only the white and light-green parts of the leeks are used in this recipe. Although not many American recipes make use of the dark-green tops of leeks, they're actually perfectly edible! Slice them super-thin and fry in oil to make leek oil and crispy leeks, both of which you can use to top a variety of dishes.
When it comes to choosing which potato to use for vichyssoise, you can opt for Yukon golds, plain old russets, white potatoes, or a mix. Avoid red potatoes because they're waxier and retain their shape well during cooking, which means less creamy results when it comes to making soup.
