Did you know?

When life hands you lemons, the saying goes, make lemonade. The message of this zingy aphorism is to take situations that are metaphorically sour and make them sweeter. You could do this by squeezing entire lemons to restore some excitement and enjoyment to your life, but you could also just take a little of the zest. Zest of course, refers to tiny pieces of citrus rind that are used to brighten, or enhance, the flavor of food and beverages. English speakers adopted the French word zest (zeste in modern French) in the late 1600s with this meaning, but it didn’t take long for them to spice up their language with an additional sense referring to any quality that adds enjoyment to something in the same way that the zest of a citrus fruit adds flavor to food. Later they extended the word to gusto—that is, enthusiastic enjoyment—itself, whether it be gustatory or not.

Etymology

from obsolete French zest (now zeste) "orange or lemon peel used for flavoring"

Word Origin

Zest was borrowed into English in the 17th century from the French zest (now spelled zeste), meaning "an orange or lemon peel." Where the French got the word we do not know. The peels of oranges and lemons are sometimes used to add flavor to food and drinks. The earliest uses of zest in English refer to the peel of such fruit used in this way. By the early 18th century, however, zest had developed another meaning. It was used to refer to a quality that adds enjoyment to something, in the same way that the zest of an orange or lemon adds flavor to food.
