Some other interesting points about canning include –
Can food be re-canned if the lid does not seal?
If discovered within 24 hours, it can be re-canned. Remove lid, check that isn’t anything wrong with the jar, and then find the lid manufacturer’s instructions of re-canning using their lids.
If canned foods have been frozen during storage, are they safe to eat?
Freezing will be fine for the food in side the jar but it can break the jar or seal. You are better off putting the canned goods in a pantry.
Is it safe to process food in the oven?
No, please do not process in the oven. There is a higher chance of jars exploding in the oven and the temperature can vary too muc.
Is it all right to reuse jar lids and bands?
No, do not use lids a second time but bands can be reused unless they are heavily rusted or bent.
When In Doubt, Throw It Out
Remember, when in doubt, throw it out. If you canned your jam and you think something is wrong, chances are it is. For your safety, don’t eat it. These problems can include –
- The container is leaking, bulging, or swollen
- The container looks damaged, cracked, or abnormal
- The container spurts liquid or foam when opened
- The food is discolored, moldy, or smells bad
Trust your gut and play it safe when it comes to canning goods at home.
