Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Plums
- Provide the main fruit flavor and body of the preserve as they cook down.
- Sugar
- Adds sweetness and helps preserve the fruit while it thickens.
- Lemons
- Their acidity helps pectin in the fruit set the preserve.
- Oranges
- Add citrus aroma and acidity, with the rind contributing fragrant oils.
- Raisins
- Add concentrated sweetness and a chewy texture.
- Pecans or english walnuts
- Add crunch and a toasty, rich flavor that contrasts with the soft fruit.
The step that matters
Cook for the full time. The mixture thickens as water evaporates and sugar and fruit pectin set together. Acid from the citrus helps the pectin gel. Stopping early leaves the preserve runny, while cooking too long can scorch the sugar and darken the flavor.
Swap the pecans
