The tiny, razor-sharp teeth of a zester make it the perfect tool for grating citrus fruit.
Why It's So Great
When you zest a citrus fruit -- that is, grate the outer layer, or colored part, of its skin -- its aromatic oils are released. These oils give the zest its intense flavor. A zester, like the one from Microplane pictured here, is easy to use, requiring almost no pressure. To release the bits of zest that get caught in the holes, tap the zester on the counter.
A zester can do a lot more than zest fruit: Use it for grating hard cheeses, such as Parmesan, Pecorino, and Romano, or for grating nutmeg, chocolate, and ginger.
