Damson Plum Jam Recipe

Wash plums, add the water and cook the fruit until the skins are soft. Cool and remove the seeds. Measure and add 2/3 as much sugar as fruit. Stir mixture over low flame until sugar is dissolved. Boil rapidly until mixture is thick and clear. The flavor of the plums should be practically unchanged and the color a rich sparkling red. Pour into sterilized jars and seal while hot.
