Any suggestions for what to do with my plum harvest?

I was late getting the net over my plum tree and thought I would lose most to fruit flies. Fortunately I was wrong! However I now have many plums I didn’t plan for.

There is probably close to 10kg, I’m planning to eat some fresh, make jam and a plum crumble but I will still have quite a lot of excess.

What do you guys do with a glut of plums ?

Thanks in advance!
