My wonderful sister in law gave me a heap of plums so I made up some jam. For those in the USA plum jelly.
I only used up half the plums she gave me and I got 10 jars, and lots still left to eat.
Warning this is what happens when the jam spits at you. Very painful and Im sure I will get a scar as a reminder.
but all in all the jam is worth it as I am onto my last jar from last years crop.
