Rasp Graters

Published March 1, 2007. From Cook's Illustrated.

We put three new rasp-style graters through their paces to see how they compare to our long time favorite.

Overview:

Update: September 2013

The Edgeware Better Zester has been rebranded as the KitchenIQ Zester, and is now dishwasher-safe. Its rating has not changed.

Update: July 2013

We tested the Edgeware Better Zester, which sports a built-in squeegee that scrapes off the grated goods and deposits them in an attached container. (Whatever you grate on a Microplane often clings to the back of the blade, especially sticky ginger and garlic.) While the Edgeware’s grating surface worked just as well as the Microplane’s, some testers preferred the latter’s wider plane and simpler design—just a single piece of steel versus the Edgeware’s steel blade set in a plastic frame (chocolate and cheese became trapped in the crevices where the plastic and metal met). We liked the Edgeware enough to recommend it, but it isn’t a trade-up on the classic Microplane.

After several years, we have grated hundreds of pounds of hard cheese, citrus zest, chocolate, shallots, garlic, carrots, radishes, and horseradish, and our favorite rasp grater remains an excellent performer overall. Our readers agree. Seventy-five of you responded to a Web survey, and not one reported significant dulling with normal use. That said, we recently noticed that its rasp-like design was no longer unique. We put three new rasp-style graters through their paces to see how they compare.

The results? The first required massive brute strength to produce even a few wisps of grated Parmesan. The second had the opposite problem--it gripped so well that it dug into the pith of the lemon. The third felt flimsy and lacked a handle, which made it difficult to use. And our kitchen standby? It breezed through all four tasks, producing piles of cheese, chocolate, zest, and ginger with minimal effort.

That said, we do have a note from the kitchen. Both readers and test cooks pointed out that this zester breaks down hard cheese into very light, feathery shards that weigh less than cheese grated on box or rotary graters when measured by volume. For instance, our tests show that 1 ounce of Parmesan grated on the fine holes of a box grater yields 1/2 cup of grated cheese, whereas the same 1 ounce grated on a rasp yields 3/4 cup of grated cheese. When following a recipe, then, use the recommended weight of hard cheese. If the amount is given by volume grated on a box or rotary grater, increase it by half if you are using a rasp grater.

    KitchenIQ Zester

    This rasp-style grater kept up with our favorite Microplane 8.5-Inch Classic Zester/Grater as it breezed through Parmesan, chocolate, zest, and ginger with minimal effort. The squeegee and container worked perfectly to keep all the food in one place and scrape the underside of the zester clean. But food got stuck between the blade and its plastic housing; however, the grater is dishwasher-safe.
