Base or Underliner
•Leafy greens usually form the base of the salad. They add greatly to the appearance of some kinds of salads.
•Cup-shaped leaves of iceberg or Boston lettuce make attractive bases. They give height to salad and help to confine loose pieces of food.
•A layer of loose, flat leaves (such as romaine, loose-leaf, or chicory) or of shredded lettuce may be used as a base.
