How to use the Microplane Classic Zester: If you are right-handed, hold a lemon in your left hand with a side up as if it were the neck of a violin. Take the zester in your right hand and make sure the sharp edges of the cutter are aimed away from you toward the lemon. Now, stroke the zester across the lemon as if you were playing the violin. The zest collects in the upper channel. Voila! Incredible fine shavings of zest. Microplane graters and zesters feature tiny razor-like edges formed by a process called photo-etching in which holes are dissolved with a chemical. A Microplane grater edge finely slices instead of tearing or shredding. Superb, top-of-the-line Microplane graters are safe and easy to use. Dishwasher safe. 18/8 stainless steel blade made in USA.
