Blackberry Apple Jam

2 lb. cooking apples
2/3 c. water
1/2 c. lemon juice
2 lb. blackberries
4 lb. sugar

Peel and core and slice the apples. Put the apples into a saucepan with the water and lemon juice and simmer for about 10 minutes or until tender. Add the blackberry and sugar and cook, stirring constantly, over a low heat until the sugar is dissolved.

Bring to a boil and boil rapidly until the setting point is reached. Pour into warm sterilized jars and seal immediately.
