I use my grater all the time! I make pastry by grating frozen butter (makes is so light!)

And practically everything I make with beets starts out with grating and toasting them!

Here's one with grated beets and zucchini, in tacos! (with kidney beans and chipotle)

Garlic!

I try to freeze things before grating - ginger, cheese. Never thought of grating tomatoes, but would freeze them first.

I really want to get myself a Microplane - it's been about 10 years since I first declared that though, I can never quite bring myself to spend the money when I have a Microplane imposter in my kitchen. Maybe it should meet with an accident!

And I'm still mashing my garlic with a fork /facepalm

Grating a tomato? I'd try it, but I'm afraid I'd end up with a squished mess. Still... I suppose I won't know unless I try...

How, exactly, does one grate a tomato? And why would one want/need to?
Inquiring minds want to know...

I wouldn't grate a tomato on a Microplane....too fine. Use the large holes on a box grater (DON'T freeze it !). The point is to get the tomato puree with some of the juice. The skin and the seeds stay behind in your hand, and are discarded. It's a great (pun, what pun???) technique.

Grating tomatoes revolutionized my life. I never peel, just slice the stalk top part off and grate. Tomato pasta sauce in no time!

Seriously, grating tomatoes changed my life too! I usually put my box grater in a bowl, cut the tomatoes in half, and then start grating from the cut face. You don't need to peel the tomatoes; the skin sort of stays behind in your hand and actually protects your fingers from the sharp edges of the grater.

It yields a texture similar to canned crushed tomatoes, as opposed to the "strands" you get from grating, say, carrots. But for any kind of sauce or stew, it's perfect.

Now about these bananas... what's the purpose of grating a frozen banana? Do you mix it with something? Is it like a smoothie shortcut?

I love to puree a frozen banana to make an easy one-ingredient ice cream, great when topped with chocolate shavings, nuts, etc. Maybe I can try it with a grater instead of a food processor?

grating butter works great for pie crusts
i keep ginger in freezer, peeled first, then grate it when needed.
grating garlic/ginger on the microplane works grate (pun intended) for any uncooked purpose like a salad or vegetable dressing. if you're cooking it a rough chop is ok.
microplane also works for nutmeg and of course zesting.
i also use it for very fluffy grated cheese-melts instantly into a sauce. same with chocolate.
