Directions:
To every pound of plums allow a quarter of a pound of sugar. Put the sugar and plums alternately into the preserving kettle, first pricking the plums to prevent their breaking. Let them stand on the back of the stove for an hour or two, then put them over a moderate fire and allow to come to a boil; skim and pour at once into jars, running a silver spoon handle around the inside of the jar to break the air-bubbles; cover and screw down the tops.
