Thick mould on jam
« on: November 02, 2013, 09:58 »
I made some rhubarb and orange jam in the summer; all jars now have a thick layer of mould on them.  What might I have done wrong.  I used wax discs, plastic discs and rubber bands.  The discs had been in the cupboard a few years, might they have got dirty, should I have bought new?

I really don't fancy scraping the mould off and eating it.  Can I re-boil  and re-jar it?

Thanks for any advise, I'm very disappointed.  Still, I can try again next year

which recipe did you use, and did you pot and cover when the jam was hot?

It could be not enough sugar,not boiled long enough,as Mum says putting lids on not hot,moisture from a damp cupboard or steamy kitchen. I really think you need to throw it out,I wouldn't risk eating it :(

Thank you both.  I can't remember whether I put tops on hot.   I will throw it out - I needed to be told, you're right, it isn't safe to eat.

A spot of mold could be scraped off and the rest eaten, but never that much mold. It's asking for trips to the hospital.

I gave up on using wax many years ago. Now, when I bottle the jam, I put the 2 part bottling tops on the jars and put them in a boiling water bath for about 10-15 minutes and this ensures a good seal (and no mold). The jam needs to be very hot when it goes into the bottles and bottles go into the water bath within a few minutes.

Leave them and feed to the bees and wasps next year.  I've kept a few wasps happy with my failed pineapple jam this year! :D

Cheers,  Tony.

I read something from Delia once that said if you get mould on top of jam, just use a spoon to take off the top inch of jam and the rest is fine to eat. I've always done that and it's never caused me any problems.

A thin layer of mold can be dug out and the rest safely eaten, but SusieB had a thick layer of mold which makes the rest of the contents very iffy. Better to just accept the loss of a bottle than ones health.

Ditto to Trillium - we have had jars of jam nearly 5 years old with a layer of mould... just scrape it off as it's normally just a few mm deep at most and eat the rest.. Obviously if its gone off you will smell it but it should be fine.
