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 fruit. Sort and wash fully ripe peaches; peel and remove pits. Chop or grind peaches. Sort, wash, and remove any stems from fresh blueberries. Thaw frozen berries.

To make jam. Measure fruits into a kettle; add lemon juice and water. Cover, bring to a boil, and simmer for 10 minutes, stirring occasionally. Add sugar and salt; stir well. Add spices tied in cheesecloth. Boil rapidly, stirring constantly, to 9 degrees F. above the boiling point of water, or until the mixture thickens. Remove from heat; take out spices. Skim.

Fill hot jam 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.
