What each ingredient does
- Imperatrice plums
- Provide the fruit, pectin and tartness that give the marmalade its body and flavour.
- Granulated sugar
- Sweetens the marmalade and helps it thicken and set as it boils.
The step that matters
Boil the mixture quickly for 15 minutes. Sugar must be stirred in off the heat so it dissolves fully, then a brisk boil drives off water and concentrates the mixture so it reaches setting point. Too little boiling leaves it runny.
