Why do bubbles form on the jelly and how can this be prevented?

• If the pot was not held close to the top of the jar as the jelly was poured, or the jelly was poured slowly and air became trapped in the hot jelly, bubbles could form. This can be prevented by holding the pot close to the top of the jars and pouring the jelly quickly into the jar.

• Bubbles may denote that the jelly has spoiled. If bubbles are moving, do not use. You should follow the recommended methods to get an airtight seal.
