Spiced Purple Plum Jam
Description
This spiced purple plum jam recipe is the result of combining plums, fresh lemon, and warm, comforting spices for an easy, deliciously giftable jam.
Ingredients
•
3 pounds plums, pitted and chopped
•
1 lemon, zested and juiced
•
4 cups white sugar
•
3 tablespoons fruit pectin (such as Sure-Jell®)
•
2 teaspoons ground cinnamon
•
1 teaspoon ground nutmeg
•
1/4 teaspoon ground cloves
Directions
1
Inspect 6 half-pint jars for cracks and rings for rust, discarding any defective ones. Immerse in simmering water until jam is ready. Wash new, unused lids and rings in warm, soapy water.
2
Combine plums, lemon zest, and lemon juice in a wide, non-reactive 8-quart pot. Whisk sugar, pectin, cinnamon, nutmeg, and cloves together in a small bowl; stir into plum mixture until combined.
3
Bring plum mixture to a boil over high heat. Reduce heat to medium-high; cook, stirring frequently, adjusting heat as needed to maintain a gentle boil until thickened and reduced by at least ⅓, 20 to 25 minutes.
4
Pack jam into hot, sterilized jars, filling to within ½ inch of tops. Run a clean knife or thin spatula around insides of jars to remove any air bubbles. Wipe rims with a moist paper towel to remove any residue. Top with lids and screw rings on tightly.
5
Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and lower jars 2 inches apart into the boiling water using a holder. Pour in more boiling water to cover jars by at least 1 inch. Bring to a rolling boil, cover, and process for 10 minutes. Turn off heat, remove cover, and let jars stand in the cooling water to help ensure a good vacuum seal, 5 minutes.
6
Remove jars from the stockpot; rest, several inches apart, to cool completely before checking seals, 12 to 24 hours. Press centers of lids with a finger to ensure lids do not move up or down. Any unsealed jars should be refrigerated and eaten promptly. Remove rings for storage and store in a cool, dark area. Sealed jars are shelf-stable at least 1 year.
