Unsealed jar of preserves sealed itself in refrigerator over night. Safe to remove from fridge?
The jar sat on the counter all day and still did not seal properly. (The center was still popping) so I put it in the refrigerator before bed. In the morning I noticed that the the jar was sealed and the center tab didn't budge. Did the sealing process just continue in the fridge, or is the cold temp playing a trick on me and once the jar gets back to room temp, will the seal open up again?
