Directions:

Sterilize canning jars. Wash berries before crushing.

Combine berries and sugar.

Bring slowly to a boil, stirring occasionally until sugar dissolves.

Once sugar is dissolved, cook rapidly to, or almost to, the jellying point, depending upon whether a firm or soft jam is desired. As mixture thickens, stir frequently to prevent sticking.

Remove from heat and fill 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.
