What each ingredient does

Grapefruit: Provides the juicy pulp and sharp, acidic flavour that forms the body of the salad.
Crisp lettuce: Gives a cool, crunchy base that contrasts with the soft, juicy grapefruit pulp.
Mayonnaise or french dressing: Adds fat and creaminess that softens the grapefruit's sharp acidity.
