with liquid pectin
- 4 cups blackberry juice (about 3 quart boxes berries)
- 7½ cups sugar
- 2 pouches liquid pectin
Yield: About 8 or 9 half-pint jars
Please read Using Boiling Water Canners before beginning. If this is your first time canning, it is recommended that you read Principles of Home Canning.
Procedure: Sterilize canning jars and prepare two-piece
canning lids according to manufacturer's directions.
To prepare juice. Sort and wash fully ripe berries; remove any stems or caps. Crush berries and extract juice.
To make jelly. Measure juice into a kettle. Stir in sugar. Place on high heat and, stirring
constantly, bring quickly to a full rolling boil that cannot be stirred down. Add pectin and heat again to a
full rolling boil. Boil hard for 1 minute. Remove from heat; skim off foam quickly.
Pour hot jelly immediately into hot, sterile jars, leaving ¼ inch headspace. Wipe rims of jars with a
dampened clean paper towel; adjust two-piece metal canning lids. Process in a Boiling Water Canner.
