Stone Fruit Jam…. Otherwise known as Peach Nectarine Plum Jam.
I was gifted a couple bags of fruit the other day. About 6 peaches, 6 nectarines and a bag of plums. We already had apples, bananas, pineapples, tomatoes and a very full fridge. The fruit was getting overripe so I knew I had to use it up quick. Jam is always a good bet!
I didn’t really have enough of any of them to make a full batch of jam so I combined what I had and wah lah… stone fruit jam.
After my family ate what they wanted.... I ended up using about 4 peaches, 4 nectarines and 7 plums. Enough for 7 cups of fruit. After looking at some of my other jam recipes I decided on 3 cups sugar. To keep the color nice I added 3 T lemon juice.
Since this was my own creation this time I didn’t know if it would have enough pectin to jel up nice but I figured if it didn’t work I’d just call it…. Stone fruit syrup! Syrup is also always a good bet!
No fear, it turned out great. Jam it is. :)

Peaches and Nectarines -
Peel, remove from the stone and chop coarsely. I just peeled with a knife since there were
not that many fruits and they were very ripe and easy to peel. You could blanch and remove the skins that
way. See my canning peaches page for
directions on how to peel your peaches.
Plums – I ended up using a food processor to chop up the plums. I was not convinced it would break up and mash as easily as the peaches and nectarines. So I figured I'd chop them up first. When you do this, be sure you only chop them. Don't liquefy. You just want it chopped finely.
Combine all in a large stock pot and bring to a boil. Stir often.
Use a potato masher if needed to mash up the fruit.
Boil for about 20 minutes, stirring constantly. As it gets thicker test the temperature. Try to get to at least 200 degrees. This is a good gelling point.
When the jam is done fill jars leaving about ¼ inch headspace. Add canning lids and rings. Pink Tattlers are the bomb! (the bomb - my sons expression of delight)
The Pink lids were a limited edition and no longer produced. But white tattler lids can still be purchased. Check your local Ace hardware and other places where they sell canning supplies. Amazon is always a good bet too. :) Here is my review of tattler lids.
