What each ingredient does
- Fair golden pippins
- Their natural pectin turns the cooking water into a thick jelly that helps the preserves set.
- Quinces
- Supply the main fruit flavour and firm pieces that hold their shape during long boiling.
- Sugar
- Sweetens the preserves and, at high concentration, helps the syrup thicken and set.
The step that matters
Test the syrup for jelling before removing from heat. Pectin and sugar must reach the right concentration to gel. Removing the pot too early leaves a runny syrup, while boiling too long can make it stiff and sugary.
