Let me begin by saying - this soup was wonderful. It was easy to make and very tasty. All of the ingredients blended together very nicely to make this tasty soup. The ingredients are your basic soup ingredients, butter, olive oil,onions, garlic, celery, and salt. Add some fresh thyme, cauliflower, chicken or vegetable broth, and white pepper. Cook the ingredients until the cauliflower is very soft, blend and serve. I served mine with some Walnut Oil, but you can serve it plain or with a topping like grated cheese, crushed walnuts, sour cream. This soup lends itself to your imagination. For my family this recipe is a keeper. You can find this recipe on pages 68-69 in "Around My French Table."
