What each ingredient does

Plums
Provide the fruit, which softens and turns clear as it cooks in the syrup.
Sugar
Sweetens the fruit and, boiled into syrup, helps preserve it.
Water
Dissolves the sugar to form the syrup that surrounds and moistens the plums.

The step that matters

Skim the syrup clear. Scum that forms on boiling syrup can cloud the liquid and carry off-flavours. Skimming it before pouring keeps the syrup clear and the plums looking bright.
