J.,
Since I HATE to waste food and I had 2 plums and 2 nectarines that were overripe. I pitted them (skin-on)and put them in a small saucepan. I added a bit of water, sugar, and lemon juice (all to taste since it was an experiment) and allowed them to simmer, mashing them all-the-while. I then made a batch of basic pancakes and used the concoction instead of syrup. It was delicious!! (While simmering, it tasted quite sweet, but on the pancakes it could have been a little sweeter. If you decide to try this, keep in mind what you'll be using it for and add a bit more sugar or a bit less.) Happy cooking!
