My mother in law sends us blocks of parmeggiano reggiano & one time I decided to use the processor to grate a whole bunch to put in a jar. It came out as these tiny little pellets. It was weird & my husband hated the texture, so I went back to using my hand held little flat grater. You get that nice airy cloud of cheese!
Yes, it’s not that great for the very hard cheeses. I use it mainly for cheddar, jack, etc. The Microplane is very good for making ‘clouds’ of very hard cheeses, too.
