To Preserve Purple Plums
Ingredients
Directions
Make a syrup with clean brown sugar.
Clarify the syrup until it is perfectly clear and boiling hot.
Pour the syrup over the plums after removing any unsound ones and stems.
Let the plums sit in the syrup for two days.
Drain the syrup, make it boiling hot, skim it, and pour it over the plums again.
Let the plums sit in the syrup for another day or two.
Put the plums in a preserving kettle over the fire and simmer gently.
