Yield: About 8 or 9 half-pint jars
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 Jelly—Sterilize 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.
