The traditional cucumber sandwich is composed of paper-thin slices of cucumber placed between two thin slices of crustless, lightly buttered white (or wheat in some cases) bread. The traditional cucumber sandwich is of British origin. Modern variants (largely of American origin) exist, involving cream cheese, chopped dill or spices, brown bread, salmon, and even bread with crusts left intact. One specific American variant includes benedictine, a green soft spread based on cucumbers and cream cheese. Cucumber sandwiches are most often served for a light snack or at afternoon tea, a formal light meal served at four in the afternoon or early evening before the main supper.
