I use two methods:
Option 1: Pour in a light homemade syrup (water and a bit of sugar boiled together).
Option 2: Use the plums’ own juice by boiling some halved plums and straining the liquid.
5. Close and process the jars.
Seal tightly and process the jars in boiling water for 20–25 minutes. This vacuum-seals them.
6. Store in a cool, dark place.
That’s it! No refrigeration needed. These jars can stay perfect for 1, 2, even 3 years!
Why It Works
Plums are naturally rich in acid, which helps prevent spoilage. Combined with a sealed environment and proper sterilization, this creates the perfect preservation conditions. Over time, the flavor deepens — they taste like concentrated sunshine by the time winter comes.
A Winter Delight
I use my jarred plums in everything from cakes and sauces to simple snacks. On cold mornings, I’ll open a jar and serve the plums warm over oatmeal or yogurt. It’s like a bite of summer when the trees are bare and frost covers the ground.
Final Thoughts
Keeping fresh plums in jars isn’t just about saving fruit — it’s about extending the joy of harvest into the quiet months. If you’ve got a plum tree or access to fresh plums in season, give this method a try. You’ll be amazed how long they last — and how good they taste when you need a little sweetness in winter.
