How do I? ...Make Jam & Jelly

Making Jams and Jellies

Plum Preserves

  • 5 Cups pitted, tart plums (about 2½ pounds)
  • 4 cups sugar
  • 1 cup water

Yield: About 5 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 until sugar dissolves. Boil rapidly over high heat, about 15 minutes, almost to the jellying point (which is 8°F above the boiling point of water, or 220°F at sea level). Stir frequently to prevent sticking or burning. Pour hot preserves into hot 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.
