What Is Plum Jam?
Plum jam is a fruit preserve made by cooking plums with sugar and lemon juice until thickened into a spreadable consistency. The natural pectin in the fruit helps it set without added thickeners, and the lemon juice adds brightness and acts as a preservative. It’s a staple in many homes and pairs beautifully with sweet and savory dishes alike.

Cooking Tips
- Choose ripe, sweet plums for the best flavor. Overripe fruit works well for jam.

- Stir frequently as the jam thickens to avoid burning.
- Skim off any foam that rises during cooking for a clearer jam.
- Always sterilize jars before filling to ensure safety and shelf life.
Frequently Asked Questions
Can I Leave the Skins On?
Yes! Plum skins soften during cooking and help add natural pectin and color.
Can I Reduce the Sugar?
You can reduce sugar slightly, but it also acts as a preservative. Lower sugar may shorten shelf life.
Do I Need to Add Pectin?
No—plums are naturally high in pectin, so the jam will set on its own.
Can I Make This with Other Fruit?
Yes! Try mixing plums with apricots, peaches, or berries for a unique blend.
Can I Make This Jam Spicy?
Yes! Add a finely chopped fresh chili or a pinch of red pepper flakes while the jam cooks for a sweet-and-spicy twist that pairs beautifully with cheese boards.
