What each ingredient does
- Plums
- Provide the fruit that becomes tender and clear as it is cooked in syrup.
- Sugar
- Sweetens the fruit and, once boiled, thickens the syrup and helps preserve the plums.
- Water
- Dissolves the sugar so it can form a syrup that penetrates and coats the fruit.
The step that matters
Boil the syrup until rich and thick. Sugar concentration determines preservation. If the syrup is too dilute it will not thicken or keep the fruit well, so it should be boiled down before the plums are covered.
