5 cups sugar
1 tablespoon lemon juice
Wash and pit plums (any kind, red, italian plums, etc.)
Put through food chopper.
Add plums, lemon juice and add 2 cups sugar to each cup of chopped plums. ( I personally think that's way to much sugar so I shaved off 3/4 of a cup)
Boil 10 minutes or until sheeting occurs.
Ladle into hot jars leaving 1/2 inch headspace. Wipe rim and affix two piece cap. Process in a hot water bath canner for 15 minutes.
