About the Recipe
Ingredients
5 whole cloves
8 cups pitted and quartered plums
8 tablespoons lemon juice
8 tablespoons water
1 (1.75 ounce) package powdered fruit pectin
8 cups white sugar
Preparation
Step 1
Wrap cloves in cheesecloth or a spice sack; set aside.
Step 2
Inspect 9 glass 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.
Step 3
Combine plums, lemon juice, water, and pectin in a large, deep saucepan over low heat. Bring to a boil.
Step 4
Add sugar and cloves. Cook, stirring continuously, until sugar dissolves and mixture reaches 220 degrees F (104 degrees C), 3 to 5 minutes. Remove and discard cloves.
Step 5
Pour jam into sterilized jars. Wipe any drips off lip of jars, and add lids. Place on a damp towel to cool and self-seal; you will hear a popping sound as jam cools, about 2 hours.
