Clove Spiced Plum Jam Recipes

Steps:

• Place the plums, pineapple, apple juice, orange juice concentrate, and lemon juice into a large pot over medium-low heat, cover, and cook until the plums are soft, 15 to 20 minutes. Mash the plums and pineapple with a potato masher until thoroughly broken up, but leave small chunks of fruit in the mixture. With the fruit mixture at a slow simmer, stir in the cloves, allspice, pectin, and butter (to reduce foaming). Raise heat to high and bring the mixture to a full, rolling boil for 1 minute, stirring constantly. Mix in the sugar, stirring constantly, and cook for 1 more minute at a full, rolling boil. Remove from heat, stir in red food coloring until even in color, and skim off any foam.
• Sterilize 12-ounce canning 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 1/4 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.

Steps:

• Submerge 6 empty half-pint jars on a rack in a large pot of water. Cover and bring to a rolling boil, then reduce heat to low to keep jars warm until ready to fill.
• Tumble plums, lemon zest, and lemon juice into a wide, nonreactive 8-quart pot. Whisk together sugar, pectin, cinnamon, nutmeg, and cloves in a small bowl, then stir into pot until combined.
• Bring to a vigorous boil over high heat. Reduce heat to medium-high; cook, stirring frequently and adjusting heat as needed to maintain a gentle boil, until volume has reduced by at least one-third, 20 to 25 minutes. Remove pot from heat and check for set.
• Working with one jar at a time, remove empty jars from canning pot. Using a wide-mouth funnel, carefully ladle jam into jars, leaving 1/2 inch for headspace. Use a clean wooden chopstick to work air bubbles out of jars. Check headspace again and add more jam if necessary to bring to 1/2 inch from the top.
• Wipe jar rims, apply lids and bands (not too tightly), and return jars to canning pot; cover pot and return water to a rolling boil. Process 10 minutes. Turn off heat, remove pot lid, and let jars stand in the cooling water 5 minutes to help ensure a good vacuum seal.
• Move jars to a folded kitchen towel or wooden cutting board to cool completely before checking seals. Any unsealed jars should be refrigerated and eaten promptly. Store sealed jars in a cool, dark place. They are shelf-stable at least 1 year.
