Is there a way to recover hardened Pecorino Romano? I've had a wedge of Pecorino Romano wrapped in plastic wrap in the fridge for a while.  There are many of you out there that probably have had the same problem.  :)

I actually cut a small piece and it was quite crunchy! I tried to grate it and it's no longer crumbly. So it's quite hard to grate. The cheese still tastes good, though.

Is there a way to get it back to its slightly softer and crumbly consistency?
I don't think you can rescue it, but you can use it. Try putting it into a vegetable soup; you'll find that it adds a bit of body as well as flavour. You can also do this with the left-over rinds of any hard cheese.
