What each ingredient does
- Quinces
- Firm fruit that softens into tender pieces and turns rosy during long, slow cooking.
- Sugar
- Adds sweetness and, dissolved into the syrup, helps preserve the fruit by drawing out its water.
The step that matters
Skim the syrup until clear. Foam and impurities rise to the surface as the syrup boils. Skimming them off keeps the syrup clear and bright, and stops off flavours from settling into the finished preserve.
