The lemon fork is a small (4+ inches long) serving utensil that is used to move lemon slices. Lemon forks have three long tines, with the outside tines splayed; ostensibly this arrangement helps to release more juice. Lemon forks became popular in the last quarter of the 19th century alongside other specialized utensils, such as asparagus tongs. One early 20th century cookbook called the lemon fork a "necessity" at the five o'clock tea party. While setting the table, the fork was placed over the slice of lemon. Unlike many specialized utensils of the 19th century, lemon forks are still used in the 21st century, primarily in restaurants.[1]
A lemon fork can double as a pickle fork and may be used to serve cucumber slices, olives, butter cubes and pats, smoked fish, and cheese cubes. One etiquette guide from 1966 stated that it is acceptable to use one's fingers to pick up lemon slices in the absence of a lemon fork.
