Plums, to Preserve

Ingredients

Directions

Prepare the syrup

  1. Combine water and sugar in a preserving pan and boil until it forms a thin syrup.

  2. Remove the stalks from the plums and prick them slightly to prevent breaking.

  3. Pour the syrup over the plums and let them sit for 2 days.

Cook the plums

  1. Transfer the plums and syrup back to the preserving pan and boil gently until the plums are tender.

  2. Carefully lift the plums into jars.

  3. Boil the syrup until it reaches the 'large thread' stage.

  4. Pour the syrup over the plums.

Seal and store

  1. Cover tightly.

  2. Store in a cool, dry place.

What each ingredient does

Plums
Form the fruit itself; gentle cooking softens them while pricking lets syrup penetrate.
Loaf sugar
Sweetens the fruit and, boiled into syrup, preserves it by drawing out water.
Water
Dissolves the sugar so it can form a syrup that the fruit absorbs.

The step that matters

Boiling the syrup to the large thread stage. Sugar concentration determines how well the plums keep. Syrup boiled too little stays watery and may spoil, while overcooking makes it too thick and hard. Judge the stage carefully before pouring it over the fruit.
