This is a sophisticated take on an American classic, the Waldorf salad. Tart crisp apples, piquant blue cheese and rich, crunchy walnuts combine to create a salad with layers of flavor and texture. Slightly sweet, deliciously tangy pomegranate molasses is the key ingredient in the vinaigrette, binding all of the elements in place of the traditional mayonnaise-based dressing. Tender baby spinach and crisp endive amp up the fresh factor of this hearty salad.
