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 — Wash and peel fruit. Cut peel in thin strips into a saucepan. Add cold water and simmer, covered, until tender (about 30 minutes). Drain. Remove seeds and membrane from peeled fruit. Cut fruit into small pieces.
To Make Marmalade —
Sterilize canning jars. Combine peel and fruit in saucepan, add boiling water and sugar. Boil rapidly over high heat, stirring frequently, until the temperature measures 8°F above the boiling point of water (220°F at sea level), about 20 minutes. Remove from heat; skim. Pour hot marmalade 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 preferably.
