Making Jams and Jellies

Damson Plum Jam
without added pectin

  • 5 cups coarsely chopped Damson plums (about 2 pounds)
  • 3 cups sugar
  • ¾ cup water

Yield: About 6 half-pint jars

Please read Using Boiling Water Canners before beginning. If this is your first time canning, it is recommended that you read Principles of Home Canning.

Procedure: Sterilize canning jars. 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). As the mixture thickens, stir frequently to prevent sticking or burning. Remove from heat and pour hot jam into hot, sterile 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 Canner.
