Zester

Zester: A zester is a kitchen utensil to make zest (duh). Since zest is simply orange or lemon peel, the market is flooded with a wide variety of zesters. This is because complex problems yield very few solutions (e.g. computer operating systems, DNA, intelligent life), while simple problems yield a surplus of solutions (e.g. mouse traps, can openers, vegetable slicers). Interestingly, the first definition for zest is the lemon peel, dating from the 17th century. The more common contemporary uses for zest are metaphors.

In vain had she once attempted to understand how a zester featured in a meal of shepard's pie and green salad.
