We got a bag of purple plums from our CSA that have a great flavor and seem ripe, but that are very tart. I'm the only person in the family who really likes sour fruit, and they are pretty sour even for me, so we are not going to get through them eating them out of hand.
What are some good fast and simple ideas for cooking them? A compote? Can I make something like apple sauce?
EDIT: Speed and simplicity are important considerations. Homemade jam is delicious, and I know how to make it, but jam-making isn't something I am going to do after I get home from work to use up some extra fruit.
