Ingredients

• 4 cups plums (pitted and chopped)
• 3 cups granulated sugar
• 0.5 cups water
• 1 package powdered pectin
• 2 tablespoons lemon juice

Directions

Step 1

Sterilize jars and lids by boiling them in a large pot of water for 10 minutes. Keep them hot until ready to use.

Step 2

Place the pitted and chopped plums into a large, heavy-bottomed pot. Add the water and bring to a simmer over medium heat.

Step 3

Cook the plums for about 5 minutes, stirring occasionally, until they are soft and begin releasing their juices.

Step 4

Stir in the powdered pectin and lemon juice. Mix thoroughly to dissolve the pectin.

Step 5

Bring the mixture to a full rolling boil over high heat, stirring constantly. A full rolling boil is one that does not stop bubbling when stirred.

Step 6

Add the granulated sugar all at once, and stir to combine.

Step 7

Return the mixture to a full rolling boil. Boil vigorously for 1 minute, stirring constantly, then remove from heat.

Step 8

Skim off any foam from the surface of the jam with a spoon.

Step 9

Ladle the hot jam into the sterilized jars, leaving a 1/4-inch headspace. Wipe the rims clean with a damp cloth, and secure the lids and bands until fingertip-tight.

Step 10

Process the jars in a boiling water bath canner for 10 minutes, ensuring the water covers the jars by at least 1 inch.

Step 11

Carefully remove jars from the water and let them cool on a towel or rack undisturbed for 12–24 hours. Check the seals by pressing the center of each lid; it should not flex up and down.

Step 12

Store sealed jars in a cool, dark place for up to 1 year. Refrigerate any unsealed jars and consume within 3 weeks.
