Can anyone suggest a way to salvage frozen chicken stock in a cracked glass jar? I overfilled two of my jars on my last stock and they've cracked. I even let them freeze without the lids so they don't crack right off the bat...but i guess i just overfilled them, so even putting the lids on once they were frozen, they still cracked. Large cracks. Can i try to peel the glass off, defrost the stock and run it through cheesecloth to get out any shards? Or should i just give up and throw them away? Any suggestions would be most appreciated.
