Jam (def.): A preserve of whole fruit, slightly crushed, boiled with sugar.
The plums are ripening and my new favourite thing to do in the kitchen is to make jam!
I have a pantry full of white plum preserve, and am now (impatiently) waiting for the blood plums to be ready so I can see what they're like as jam too.
There's not much better than homemade jam made with homegrown fruit on homemade fresh bread with the biggest dollup of cream spread over the top...
