Wild Plum Preserves

Ingredients

Directions

Prepare the plums

  1. Scald the plums in a solution of saleratus and water to tenderize the skins and reduce the strong taste.

  2. When the skins start to break, pour off the water and drain the plums.

  3. Remove the pits and weigh the plums, using an equal weight of sugar.

Make the syrup and preserve

  1. Place the sugar over the plums with a little water and bring to a boil, skimming off any foam.

  2. Add the plums to the boiling syrup and cook until tender, then remove the plums.

  3. Boil the syrup down until it reaches the consistency of molasses, then pour it over the plums.

  4. No sealing is required.

What each ingredient does

Plums
Provide the fruit, whose flesh softens and whose skins are tenderized by the alkaline scald.
Saleratus (baking soda)
Alkaline solution that softens the skins and reduces the plums' strong, bitter taste.
Sugar
Sweetens the fruit and, boiled down into syrup, thickens and preserves it.

The step that matters

Boiling the syrup down. Sugar must concentrate until it reaches molasses-like thickness; if it is under-boiled the syrup stays thin and the preserve may spoil, while over-boiling can scorch or make it too stiff.
