Preserving Giant Puffball

[CostFamily]

I was fortunate today to find a beautiful 4 lb giant puffball in prestine
condition.   I found it in the Wasatch mountains  East of Ogden Utah, (about 5
miles from where the mens downhill olympic ski races took place)  No maggaots
or signs of deterioration.  I plan to cut it up and cubes and freeze it for use
latter on.  Is this a good way to preserve puffballs or is there a better way?
