How can I save unset jam?

[peripathetic]

I suspect that I overboiled my attempt at plum jam. Is there any way of converting 11 jars of sweet plum sauce into something that will spread rather than pour?

If your jam is runny it means it didn't heat to setting point, the best thing is to boil it again until setting point is reached. You might want to add some lemon juice to help it along.

Good advice previously, but you could also add one package of pectin (we sue Sure-Jell here int he U.S.) for each 4 cups of jam... bring to a boil, stirring until pectin is incorporated thoroughly... reseal in the jars, but use new lids...

A true example of the special relationship between the UK & the USA.
Jam makers of the world unite!

You could add double cream and churn to make plum ice cream?
