What each ingredient does
- Quinces
- The main fruit; it cooks until tender and firm while holding its shape in the syrup.
- Pippins
- Provides pectin, the natural setting agent that thickens the jelly used to preserve the fruit.
- Sugar
- Sweetens the syrup and helps preserve the fruit while it thickens into a set syrup.
The step that matters
Test the syrup for jelliness before removing from heat. Pectin sets only at the right sugar and concentration. Removing the syrup too early leaves it runny, while cooking it too long makes it stiff and cloudy.
