Step-by-Step: How to Make Plum Jam

Making plum jam from scratch is simpler than you think. Here’s a step-by-step breakdown:

1. Prep the Plums

• Wash and pit the plums. No need to peel.
• Chop them into small chunks.
• Optional: Mash slightly with a potato masher if you like a smoother jam.

2. Combine Ingredients

• In a large pot, add plums, sugar, and lemon juice.
• Stir to combine, then let the mixture sit for 15–20 minutes to draw out the juices.

3. Cook the Jam

• Bring the mixture to a boil over medium-high heat.
• Stir frequently to prevent sticking or burning.
• Cook for 20–30 minutes, skimming off any foam.
• Use a chilled plate or thermometer (target 220°F) to test for set.

4. Blend or Leave Chunky

• For a smoother texture, blend the jam with a hand blender before transferring to jars.

5. Jar and Seal

• Use sterilized jars and ladle hot jam into them.
• Wipe rims clean and seal tightly.
• Process in a boiling water bath for 10 minutes for longer shelf life.

Tips for Perfect Plum Jam

• Use ripe but not overripe plums for the best flavor and pectin content.
• Don’t skip the lemon juice—it helps the jam set and balances the sweetness.
• Stir constantly near the end to prevent burning.
• Always use clean, sterilized jars and follow safety practices.
