Tools and Ingredients You’ll Need

To get started with quick and easy plum jam, gather the following:

Basic Tools:

• Large heavy-bottomed saucepan
• Wooden spoon
• Sterilized jars and lids
• Funnel (optional but helpful)
• Potato masher (for chunkier jam)

Core Ingredients:

• 2 pounds of fresh plums (pitted and chopped)
• 1½ to 2 cups sugar (adjust to taste)
• 2 tablespoons lemon juice (helps with setting)
• Optional: cinnamon, vanilla, or ginger

Preparing Your Plums

Why You Don’t Need Pectin

Plums are one of those lucky fruits naturally high in pectin. This means you can skip store-bought pectin and still get a beautiful, gelled consistency. Adding lemon juice boosts the pectin effect and also balances the sweetness.
