Cucumber sandwich

This simple, elegant staple of the famous British afternoon tea, known as cucumber sandwich, is a concoction made with crustless triangles of lightly buttered white bread that is filled with paper-thin cucumber slices, a little bit of salt, and a dash of lemon juice.

The Brits invented it during the Victorian period, when it was mainly popular among members of the upper class. Today, there are many variations on the original, with added tuna, eggs, cream cheese, and mayonnaise.
