What each ingredient does
- Golden pippins
- Their natural pectin helps the cooking liquid set into a jelly.
- Fine sugar
- Sweetens the syrup and, with the pectin, helps it gel while also preserving the fruit.
- Quinces
- Firm fruit that holds its shape through long cooking and turns rosy as it cooks.
The step that matters
Testing the syrup for jellied consistency. Pectin and sugar set into a gel only at the right concentration. Stopping too early leaves the syrup runny, while cooking too long makes it stiff and cloudy.
