With a citrus zester: Hold the lemon in one hand and drag the zester across the skin of the lemon. This results in long, slender curls.
With a microplane: Drag a whole lemon over the microplane, rotating the lemon slightly as the zest is removed. Continue in this manner until all of the lemon color is removed. It’ll take just a few minutes to zest an entire lemon.
With a box grater: Drag a whole lemon over the smallest holes on the grater, rotating the lemon slightly as the zest is removed.
With a vegetable peeler: Carefully remove just the yellow portion of the skin, creating lemon ribbons. You can use the ribbons in strips, or make smaller pieces by chopping them with a knife.
Notes
This flavorful ingredient is best used fresh, but if you have more than you can use, store it in an airtight container in the refrigerator for up to a week, or freeze for up to a month.
