Cook the quinces

What each ingredient does
- Quinces
- Provide the fruit and its firm flesh, which holds shape and gives the preserve its body.
- Sugar
- Sweetens the preserve and helps it set into a thick, jelly-like syrup.
- Pippins
- Release natural pectin as they boil, which helps the syrup thicken and jell.
The step that matters
Testing the syrup for jelling. Pectin and sugar set only at the right concentration. Removing the syrup from heat too early leaves it runny, while cooking too long can make it stiff.
