This is one of those gigantic (32 oz) packages of Precious low-moisture part skim mozzarella cheeses. I bought it when I had planned to make several lasagnas then ended up not making all of them and forgot about it. I honestly can't remember how long it's been there - maybe 4-5 or more weeks. I cut into it, then put the whole thing in a sealed ziploc (still in the original Precious plastic packaging.) It looks fine - when it goes bad, will I see visible mold? Can I freeze it now, or would that be a bad idea? Thanks!
