Plum Jam with powdered pectin

  

Quantity: 9 half-pints

Jar size: Half-pints or pints

Ingredients:

6 cups crushed plums (about 3½ pounds plums)
1 package powdered pectin
8 cups sugar

Instructions:

1. Sterilize canning jars and prepare two-piece canning lids according to manufacturer's directions.

2. Sort fully ripe plums, wash, cut into pieces, and remove pits. If flesh clings tightly to pits, cook plums slowly in a small amount of water for a few minutes until they are softened, then remove pits.

3. Crush fruit and measure into a kettle. Add pectin and stir well.

4. Place on high heat and, stirring constantly, bring quickly to a full boil with bubbles over the entire surface.

5. Add sugar, continue stirring, and heat again to a full bubbling boil. Boil hard for 1 minute.

6. Remove from heat; skim foam.

7. Fill hot jam immediately into hot, sterile jars, leaving ¼ inch headspace.

8. Wipe rims of jars with a dampened clean paper towel; apply two-piece metal canning lids.

9. Process in a boiling water canner according to the recommendations. Let cool, undisturbed, 12-24 hours and check for seals.
