Yield: About 8 half-pint jars
Procedure: Sterilize canning jars. Combine all ingredients; bring slowly to boiling, stirring occasionally until sugar dissolves. Cook rapidly to, or almost to, the jellying point (which is 8°F above the boiling point of water, or 220°F at sea level). Stir constantly to prevent sticking or burning. (See Testing Jelly Without Added Pectin.)
Pour hot jam 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.
