  • 2 cups water
  • ½ cup seedless raisins
  • 1 package powdered pectin
  • 7 cups sugar
  • ½ chopped nuts

Yield: About 8 or 9 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 and prepare two-piece canning lids according to manufacturer's directions.

To prepare fruit. Sort and wash plums, remove pits. Chops plums fine. Peel and chop oranges. Shred peel of ½ orange very fine. Combine orange and peel, add the water, cover, and simmer for 20 minutes.

To make conserve. Measure chopped plums into a kettle. Add orange, raisins, and pectin and stir well. Place on high heat and, stirring constantly, bring quickly to a full boil with bubbles over the entire surface. Add sugar, continue stirring, and heat again to full bubbling boil. Boil hard for 1 minute, stirring constantly. Stir in nuts. Remove from heat; skim.

Fill hot conserve immediately 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.
