Cut plums
into quarters, remove stones. Combine plums and the water in large
saucepan; bring to boil. Reduce heat; simmer, covered, 1 hour. Add juice
and sugar; stir over heat, without boiling, until sugar dissolves. Boil,
uncovered, stirring occasionally, about 20 minutes or until jam jells
when tested. Pour hot jam into hot sterilized jars; seal while hot.
