How can you make the most of this handheld wonder in your cooking? Read on.
What it is. A rasp-style grater (also sometimes referred to as a zester) is a long, skinny tool. Attached to the handle is a blade covered in tiny U-shaped teeth. Imagine your box grater but on a much smaller scale. It’s beautiful in its simplicity and utility, really. Plus, they’re pretty affordable, with most brands setting you back between $10 and $20.
The obvious stuff to use it on. It’s an ideal tool for when you want a very fine texture of an ingredient. I use mine the most for citrus zest. After that, I favor it for grating ginger, frozen for extra ease. You can grate garlic, too. It is pretty much the only tool you’ll want to pull out for freshly grated nutmeg (or cinnamon). Create easy, elegant garnishes for dishes with a feathery pile of grated Parmigiano-Reggiano or chocolate.
The less obvious stuff. I’ve picked up a lot of tips from pastry chefs, but one of my favorites comes from Tiffany MacIsaac of Washington’s Buttercream Bakeshop, who clued us in that a rasp-style grater is ideal for smoothing off the edges of cakes. You know how sometimes you get a thin lip where the batter baked crispier against the pan? Grab your grater and get sawing (gently). Microplane endorses a similar concept for getting rid of burned parts of toast or cookies. And here’s one the company suggested that I never would have thought of: Shave down wine corks so they can fit back in the bottle. If you happen to have salt-cured egg yolks on hand, grate away. Want to add some heat to a dish? A little grated chile pepper will do the trick.
How to use it. Decide how to use it based on comfort and what you’re grating. When zesting citrus, I like to hold the fruit in one hand and grate with the teeth facing up so that the zest collects in the channel and I can see how much I’ve gotten. Other times, I will grate directly into a bowl or onto the food, as with cheese. For citrus, I usually move the grater over top of the food. For nutmeg or chunks of cheese, I like to move the food and keep the grater stationary. Do what feels natural and safe. One thing to keep in mind regardless of how you work it is the direction you grate in. The teeth do their job when the food comes across them against the grain so that they can grip and grate the food. America’s Test Kitchen suggests not pressing down on the blade as you swipe back for another pass. Applying pressure that way can flatten the teeth and make them less effective. Microplane says if the grater produces more of a wet paste, it may be time for a replacement. Eventually, the teeth can be dulled (and not resharpened).
Be safe. A rasp-style grater is not quite so scary as say, a mandoline, but you should still use caution. First, know when to stop grating. You are not going to get every last bit of ginger or nutmeg. Stop while you’re ahead, keeping your fingertips well clear of the blade. For extra safety, you can wear a cut-resistant glove. To avoid a different type of injury (and to keep the teeth sharp), always store the grater in the protective case it came in. If your case has been lost or never existed, consider keeping the grater in a place where an errant hand can’t get cut. Or fashion your own sheath, even if it’s just a dishtowel secured with rubber bands.
Caring for it. I have found it’s easier to clean a rasp-style grater as soon as you’re done using it. Trying to pry dried-up ginger fiber out of the teeth? No, thanks. Often tapping out any excess food and a quick wash under running water is all you need. Use a brush to loosen any food that may be stuck in the blade. As with knives, dry immediately. Avoid soaking, Microplane director of sales and marketing Lisa Egger told Food 52 earlier this year, since water can find its way into the handle. Microplane says its zesters are top-rack dishwasher safe, although ATK points out that the blade can be dulled by being knocked around. Honestly, I’d rather not be reaching into a dishwasher with a sharp tool inside, and I’d prefer to save the precious space for other things that are more annoying to clean in the sink.
