6 lbs. prune plums or 2 boxes of prunes for a small batch
Sugar to taste if necessary

Wash plums and remove pits, cut up into small pieces. Put into heavy pot cook on top of stove with low flame or in oven at 250 degrees all day. Maybe 2 days. Cook until very stiff. Add a little sugar if it tastes sour. Stir often as it will scorch if cooked too fast. Use prunes in same manner as plums. Put into jars and seal as you would jelly. Use as a bread spread or as a pastry filling.
