Homemade Plum Jam
This is one of the easiest jams you can make. You don’t need pectin and it cooks pretty quickly into sweet, thick jammy goodness. I prefer a softer set, so I stopped cooking mine a little sooner than you might prefer. I like a jam that spreads easily, even after it has been opened and stored in the fridge. I hadn’t made plum jam in a long time. That will change after this. I love this jam.
Because I hadn’t made it in years, I did a test with just a couple of plums. The flavor was great, but some of the pieces of the peel seemed too big. I could see them in the finished jam. To insure the skins got chopped up, I cooked my jam for awhile then used an immersion blender to smooth it out. This is just a cosmetic preference. You can just cook down chopped up plums and they will be fine.
So here is the recipe. I got it from the NCHFP website. The only changes I made was to up the processing time to 10 minutes, so I didn’t have to sterilize the jars. I also let the jam sit in the canner a few extra minutes to prevent siphoning.
Plum Jam
2 quarts chopped, pitted tart plums (about 4 pounds) – any plums will work
6 cups sugar
1½ cup water
¼ cup lemon juice
Combine all ingredients; bring slowly to boiling, stirring occasionally until sugar dissolves. Cook rapidly to, or almost to, the jellying point (which is 8°F above the boiling point of water, or 220°F at sea level). Stir constantly to prevent sticking or burning.
Pour hot jam into hot jars, leaving ¼ inch headspace. Wipe rims of jars with a dampened clean paper towel; adjust two-piece metal canning lids. Process in a boiling water bath canner for 10 minutes. Turn off the heat and allow jars to remain in canner 5 minutes before removing. Set jars on cooling rack or towel in a draft free place while they cool down. Check seals once jars are cool. Yield: About 8 half-pint jars.
