I did it. I made plum jam. Wow, it's sweeeet; tasty, but a bit sweet to my taste. I would love to have a clear fruit flavor come through more. Ingredients: sugar, fresh organic plums, filtered water. Nice and simple. If you have not tasted handmade jam I highly recommend it. And if you have wanted to try making jam but have put it off, set some time aside and give it a go. Honestly, when I was pitting 2.5 pounds of plums I wondered what I had gotten myself into. But all in all, it's worth it. It takes a bit of time but such sweet rewards.
