This creamy hazelnut and sage cauliflower soup is a comforting and flavorful dish. The cauliflower is cooked until tender and then blended with roasted hazelnuts, giving the soup a rich and nutty flavor. Fresh sage leaves are added for a hint of earthiness. The soup is finished with a touch of cream, which adds a creamy and velvety texture. Serve this soup as a starter or a light meal, and garnish with additional roasted hazelnuts and sage leaves for an extra crunch and aroma.
