Ladybug is right. You can buy a zester, or you can just grate the lemon peel. If you are grating, use a fairly fine grater for smaller zest. You probably don't want big chunks in your recipe. I have the zester and it works great, also for cheese, and for chocolate!!! But I was told to never put it in the dishwasher, always rinse it by hand.
