zester

A zester is a kitchen tool designed to remove zest, the thin outer colored layer of citrus fruit such as lemons, limes, oranges, and grapefruits. Zest contains the fruit’s essential oils and bright aroma, offering flavor without the bitterness of the white pith beneath the peel.

Two common designs are used: microplane or perforated grater-style zesters that shave very fine zest, and channel or ribbon zesters that produce thin strips or curls. Some models resemble a small knife or paddle with sharp slots for longer zest. The choice affects the texture and amount of zest obtained.

To zest, roll the fruit on a cutting board to loosen the oils, hold it steady, and drag the tool across the peel with light pressure, turning the fruit as needed. Stop before reaching the white pith, which is bitter. For most recipes, fresh zest is preferred; if wax is present, wash the fruit or briefly scrub before zesting.

Uses include flavoring batter and doughs, dressings and marinades, sauces, and cocktails. Zest can be finely grated for a subtle aroma or peeled into ribbons for garnish. Lemon zest is the most common, but lime, orange, and grapefruit zest are widely used.

Care and storage: rinse and dry after use; sharp zesters should be dried promptly. Some models are dishwasher safe, but hand washing helps preserve the blade. Fresh zest can be stored briefly in the refrigerator, or frozen for longer storage.
