What each ingredient does
- Quinces
- Provide the main fruit flavour and firm texture that holds its shape in the preserve.
- Pippins
- Release natural pectin into the water, which helps the mixture thicken and set.
- Sugar
- Sweetens the preserve and, at high concentration, helps preserve it and aid setting.
The step that matters
Test syrup for jelling before removing from heat. Sugar, pectin and acid must reach the right balance to set. Removing the syrup too early leaves it runny, while overcooking makes it stiff and dark.
