What each ingredient does
- Pineapples
- Provide the fruit base, with natural acidity and flavour that set the marmalade's character.
- Sugar
- Sweetens the marmalade and, with boiling, helps thicken it and preserve the fruit.
The step that matters
Boiling the sugar and water to a thread. Sugar syrup must reach the right concentration before the fruit is added. Boiling it to a thread stage ensures enough sugar is dissolved and concentrated to help the mixture set and keep well.
