Is this jam safe to eat?

[scampadoodle]

I made a batch of summer fruit jam in June, using screw-top jars (from Lakeland - have used them many times before) and one small kilner jar. The jam so far from the screw-tops has been lovely but I opened the kilner yesterday and there was a bit of mould (about 2p piece-sized) on the edge of the wax disc and a much smaller bit on the surface of the jam under the mould on the disc. I threw away the disc and scooped off the mould from the jam, also removing a large margin around it. I had a taste from the jar & it tastes fine (I've now put it in the fridge).

Is it safe to eat? I read somewhere once that once there's a bit of mould it's actually all the way through even if you can't see it because of the spores. Is this true?

It's the nicest jam I've ever made

The official advice is not to eat it, but TBH my mother would always scrape off a thickish layer if jam started to go mouldy and it never seemed to do us any harm.

Maybe you could use it in something cooked - jam tarts or a sponge pudding or suchlike?

That's a good idea, thanks. I don't know why I'm being squeamish as I'm always scraping the mould off pesto before using. Maybe because it's been in a cupboard, not the fridge?

If the jam is fairly well set, the sugar content should be fairly high, so it should keep fairly well. Not only would I eat it, I would quite happily serve it to visitors provided I had scraped off any visible mould and it tasted OK (and I had waited 24hrs to see if it had any adverse effect on my bowels). You only made it in June (this year, I take it) so it should be OK.
