Sometimes I need to shred a block of a soft cheese such as mozzarella, or cheddar. When I use my grater, the cheese starts to get kind of chunky as I'm grating it. I end up wasting a lot of cheese when I try to grate it.
It never happens when I grate harder cheeses like peccorino.
Is there a way to grate softer cheeses without ending up with big pieces of wasted chunks? Is there a particular grater that works better for softer cheeses?
I currently use a mandolin grater, and not a box grater.
