    Instructions

    Glass bowl containing chopped leek, carrot, celery, and garlic next to chopped potatoes on a cutting board.

    Roughly chop the leeks, carrots, celery, and garlic. Peel the potatoes, cut them in half, and slice into thin wedges.

    Steel pot with butter melting in it.

    Melt the butter in a large saucepan over medium heat.

    Steel pot with chopped vegetables and spices.

    Then add the leek, carrot, celery, garlic, bay leaf, and thyme. Cook over moderate heat, stirring occasionally, for about five to ten minutes.

    Next add the potatoes and the broth. Give the pot a good stir, cover it with a lid, and simmer the mixture for about 20 minutes or until the potatoes are very tender when pierced with a fork.

    Let the mixture stand until it is cool enough to blend. Discard the bay leaf and puree the soup with an immersion blender until very smooth. (A regular blender is fine, too, but more messy.)

    Place the smoothly blended vegetable mixture back on the stove over medium low heat and stir in the half-and-half.

    Serve the soup garnished with fresh chopped chives.

    Serving Suggestions

    • To Garnish - fresh chopped chives
    • To Drink - Riesling, Belgian ale, or dry sherry

    Equipment

    An immersion blender is extremely useful for pureeing this soup, but a regular blender or a food processor also works just fine.

    Storage

    The blended vegetable mixture can be prepared in advance and then frozen for at least a week or two. When you are ready to serve the soup, simply thaw the blended vegetable mixture in the refrigerator before heating and mixing in the Stilton and the port.
