Do I need a rasp grater if I have a regular medium microplane?
I've been zesting lots of lemons lately and I've been using my regular medium microplane. Should I be using a microplane rasp grater instead so as to avoid the pith?
ETA: It's the Microplane Fine Grater I own. Do I need a rasp grater too to zest lemons or will the Microplane Fine grater work without removing the pith?
The microplane fine grater will work without removing pith ...it's more a question of how fine you want the zest.
I'd suggest that in 99% of the uses for zest, your current microplane would be fine (pardon the pun...). And in a rare circumstance that you did want it more fine, you could run a knife over the zest to break it up a bit more.
That said I like the size & shape of the rasp better.
There are a lot of different sizes and shapes of Microplanes, so this tip may not work for everyone. But for those who have the version of the fine grater shaped like a tube, with an open area on one side and the teeth on the other:
It works beautifully if you use it as you would a bow playing the lemon like a violin, with repeated "staccato" notes: draw it across the skin, pick it up and start next to your previous stroke, and so on until you've accumulated the desired amount of zest in the trough above your "bow".
