Jam jar seal

Asked August 5, 2020, 11:57 AM EDT

My question is about the reliability of a jar lid's seal.

I made a batch of apricot jam last night. Six of the seven jars sealed before I went to bed. This morning, the lid on the seventh jar (8-oz quilted crystal Ball jar) still had not sealed. I touched it with my finger, and it pinged shut. Can I trust that this jar has sealed correctly?

Since it was only one jar. I would refrigerate it and enjoy. If not it may mold over time

Joyce, thanks for the quick reply.
