Easy Prune Plum Jam Recipes

Steps:

• Place the plums and water into a large pot, and bring to a boil. Reduce heat to medium-low, cover, and simmer for 5 minutes. Stir in the sugar, and add butter to reduce foaming, if needed. Bring the mixture to a full, rolling boil over high heat, stirring constantly, and then mix in the pectin quickly. Return the jam to a full boil, and boil for 1 minute, stirring constantly. Remove from heat, and skim off and discard any foam.
• Sterilize the jars and lids in boiling water for at least 5 minutes. Pack the plum jam into the hot, sterilized jars, filling the jars to within 1/8 inch of the top. Run a knife or a thin spatula around the insides of the jars after they have been filled to remove any air bubbles. Wipe the rims of the jars with a moist paper towel to remove any food residue. Top with lids, and screw on rings.
• Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil over high heat, then carefully lower the jars into the pot using a holder. Leave a 2 inch space between the jars. Pour in more boiling water if necessary until the water level is at least 1 inch above the tops of the jars. Bring the water to a full boil, cover the pot, and process for 10 minutes.
• Remove the jars from the stockpot and place onto a cloth-covered or wood surface, several inches apart, until cool. Once cool, press the top of each lid with a finger, ensuring that the seal is tight (lid does not move up or down at all). Store in a cool, dark area. Refrigerate opened jars for up to 3 weeks.

Steps:

• Bring plums, sugar, lime zest, lime juice, and a pinch of salt to a boil in a pot, mashing plums with a potato masher. Cook, stirring often, until mixture has the consistency of thick honey. Remove skins using a fork. Let cool. Refrigerate until ready to use (up to 1 month).

Steps:

• Pit, chop, and mash plums.
• Place in large pan over medium heat.
• Add 1/4 cup lemon juice to pan.
• Cook to a full boil. Reduce heat and cook 30 minutes.
• In separate bowl, add sugar and pectin and mix together.
• Add sugar/pectin mixture to pan. Stir.
• Bring to boil and cook for another 5 to 10 minutes.
• Remove from heat.
• Fill jars to 1/4" of top. (Makes six 8oz. jars).
• Wipe rims clean and screw on 2-piece lids.
• Submerge sealed jars into hot water bath at 200 degrees or boiling water for 10 minutes. Lids will "pop" once removed from hot water bath and you know they are sealed. Let cool on counter.

Steps:

• In large non-aluminum kettle, combine plums, water, and lemon juice. Bring mixture to boiling over high heat, stirring constantly. Reduce heat to low and cook, covered, 10 minutes or until soft, stirring occasionally. Mixture should have reduced to about 4 1/2 cups.
• Add sugar and heat mixture to full, rapid boiling over high heat, stirring constantly. Stir in pectin; return to full, rapid boiling and boil exactly 1 minute, stirring constantly. Remove from heat. Set aside 1 minute and skim off any foam that has formed.
• Meanwhile, sterilize 8 half-pint jars or jelly glasses and the necessary lids, and bands, according to manufacturer's directions. Divide jam among sterilized jars, leaving 1/8-inch space at top of jar. Wipe rims of jars to remove any jam and seal with lids and bands.
• Process jars in boiling water for 5 minutes. Remove jars, label, and store in cool, dry place

Steps:

• Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain well before filling.
• Pit unpeeled plums. Finely chop or grind fruit. Place fruit in saucepan; add water. Bring to boil. Reduce heat to low; cover and simmer 5 min. Measure exactly 4-1/2 cups prepared fruit into 6- or 8-qt. saucepot.
• Stir sugar into prepared fruit in saucepot. Add butter to reduce foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in pectin. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
• Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on towel to cool completely. After jars cool, check seals by pressing middles of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)

Steps:

• Stir together plums, sugar, and 1/4 teaspoon salt in a large heavy-bottomed pot. Bring to a boil, stirring until sugar is dissolved and mashing plums with a potato masher. Add lemon juice; continue to boil, stirring frequently, until bubbles slow, chunks of fruit show at top, and mixture clings to a spoon but falls off in clumps, 10 to 12 minutes. Skim foam from top.
• Ladle jam into clean containers, leaving 3/4 inch of headroom. Let cool completely. Cover, label, and refrigerate up to 1 month, or freeze up to 1 year.
