(Note: When peeling citrus fruits for marmalades, be sure to include some of the white membrane found just under the skin. This is where most of the pectin is located.)
Yield: About 3 or 4 half-pint jars
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.
