Or you can do what was suggested to me by some italian ladies.
Finely grate ur parmesan and the store it in the freezer and the just
take out the right amount of already grated parmesan as you need it.
Works great.
But
remember to place ur rind in a jar of olive oil in the fridge and use
pieces of it as a removable flavouring ingrediant when u make soup.
