Now foams are played out and I'm definitely not the trend follower; but i do implement when necessary. This cauliflower bisque had an amazing flavor of caramelized cauliflower florets and dark chicken stock. A vanilla bean foam was perfect to top this hor d'oeuvre. I blended some vanilla bean with hot milk and created a natural foam with an immersion blender. The essence of vanilla truly complimented the creamy cauliflower bisque as it was topped for each individual guest.
