Plum Jam without added pectin

  • 2 quarts chopped tart plums (about 4 pounds)
  • 6 cups sugar
  • 1 1/2 cup water
  • 1/4 cup lemon juice

Yield: About 8 half-pint jars

Please read Using Pressure Canners and 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 and prepare two-piece canning lids according to manufacturer's directions.

To prepare fruit. Combine all ingredients; bring slowly to boiling, stirring occasionally until sugar dissolves. Cook rapidly to, or almost to, the jellying point (which is 8F above the boiling point of water, or 220F at sea level). Stir constantly to prevent sticking or burning. (See Testing Jelly Without Added Pectin.)

Pour hot jam into hot, sterile jars, leaving 1/4 inch headspace. Wipe rims of jars with a dampened clean paper towel; adjust two-piece metal canning lids. Process in a Boiling Water Canner.
