Inversion Canning
I tried canning spiced peach jam last night with a friend, and the recipe she found called for the inversion canning method to seal the jars. I should have researched on this last night, before we canned some of the peaches... but I didn't. I haven't gone to check if all of the tops sealed properly yet, but I am wondering if it's possible to water bath them after they have set. Will that ruin the jam?
Best Answer
Yes you can reprocess them in a water bath within 24 hours, and it should not ruin the jam. According to National Center for Home Food Preservation .
Reprocessing Unsealed Jars: If a lid fails to seal on a jar, remove the lid and check the jar-sealing surface for tiny nicks. If necessary, change the jar, add a new, properly prepared lid, and reprocess within 24 hours using the same processing time. Headspace in unsealed jars may be adjusted to 1½ inches and jars could be frozen instead of reprocessed. Foods in single unsealed jars could be stored in the refrigerator and consumed within several days.
If you want to reprocess all the jars, even if they seemed to seal, make sure you remove the lids and continue from that point. Instructions for water bath canning can be found here.

Inversion canning is a method of canning that involves pouring hot canning materials (usually jams or jellies) into jars, securing the lid, and then turning the cans upside down on a towel for about 5 minutes. After the 5 minutes have passed, you flip the jars back upright and let them cool and (ideally) seal.Does inversion canning work?
It was once thought that inverting jars of high-acid foods would create a vacuum in the jars and cause the lids to seal and that this was an acceptable alternative to water bath processing the jars. This theory has been proven to be false and can lead to serious contamination of the food.Do you flip jars upside down after canning?
Ball recommends against it for seal quality reasons. They say, \u201cDo not invert, move or store jars while cooling, as this may cause seal failure.\u201d For any other type of canning (besides jams and jellies)\u2013vegetables, pickles, tomato sauces, fruit, etc.Why do you turn canned tomatoes upside down?
While turning jars upside down can produce a seal (because the heat of the product coming in contact with the lid causes the sealing compound to soften and then seal as the jars cool), the seal tends to be weaker than one produced by a short boiling water process (you should never be able to remove the lid from a home ...No Water Bath Canning
