What each ingredient does
- Quinces
- Provide the fruit body and flavor, and soften into tender pieces during long cooking in syrup.
- Sugar
- Sweetens the preserves and, dissolved in water, forms a syrup that helps preserve the fruit.
The step that matters
Cook until the quinces turn red. Quinces are firm and starchy when raw. Long cooking in syrup softens their cell walls and pectin so the fruit becomes tender, and the color deepens as its pigments develop. Stopping too early leaves the fruit hard and pale.
