Zest a lemon even if you don't have a microplane.
If you don't have a microplane (the kitchen tool similar to a cheese grater that makes it easy to zest a lemon), you can easily get lemon zest without a microplane. Use a vegetable peeler to peel the skin off, aiming to get as little of the white parts as possible, and then finely mince the zest with a sharp knife. Voila! Use the zest according to your recipe.
