How do I? ...Make Jam & Jelly

Making Jams and Jellies

Plum Jelly
without added pectin

  • Plum juice (1 pound plums and ½ cup water)
  • Sugar (¾ cup to each cup of juice)

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:

To Prepare Juice—Wash plums well. Crush fruit, add water, cover and bring to a boil over high heat. Reduce heat and simmer 15 to 20 minutes or until fruit is soft. When fruit is tender, pour everything through a double layer of dampened cheesecloth or a damp jelly bag. Suspend the bag over a bowl or pan, using a stand or colander to hold the bag. Drain the juice without pressing or squeezing, which will cause cloudy jelly. If a fruit press is used, the juice should be restrained through a jelly bag.

To Make JellySterilize canning jars. Cook juice down until thick and cherry colored. Measure juice into a saucepot, add sugar and stir well. Boil over high heat until the temperature measures 8°F above the boiling point of water (220°F at sea level), or until the jelly mixture sheets from a metal spoon. (See Testing Jelly Without Added Pectin.)

Remove from heat; skim off foam quickly. Pour hot jelly 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.
