Wild Plum Preserves
Ingredients
Directions
Prepare the plums
Scald the plums in a solution of saleratus-water until the skins begin to break.
Drain the plums and remove the pits.
Make the syrup
Weigh the plums and add an equal weight of sugar.
Add a little water and bring to a boil, skimming off any foam.
Add the plums and cook until tender, then remove the plums.
Boil the syrup down until it thickens to the consistency of molasses and pour over the plums.

What each ingredient does
- Wild plums
- Provide the fruit, which softens and holds its shape during cooking to form the preserve.
- Sugar
- Sweetens the fruit and, as it thickens into syrup, preserves the plums and gives body.
- Saleratus (baking soda)
- Alkaline solution that softens the skins so they begin to break during scalding.
The step that matters
Boiling the syrup down. Sugar syrup thickens as water evaporates and concentrates, and it must reach a molasses-like consistency to set the preserve properly. Stopping too early leaves it thin and runny, while over-boiling can scorch the sugar.
