Potato Soup with Leeks, Blood Sausage, and Parsley
The potato and the leek are happy bedfellows, as anyone who has eaten a good vichysoisse will know. Softer than potato and onion, more graceful than a chowder, warm potato and leek soup has a peaceful, almost soporific quality. A silky, cool-weather soup that somehow manages to taste creamy and rich with only the smallest amount of butter and no cream in it.
