Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Blue california plums
- Provide the fruit base and natural pectin that help the preserve thicken as it cooks.
- Sugar
- Sweetens the preserve and draws water out of the fruit, helping it thicken and keep.
- Raisins
- Add concentrated sweetness and chewy texture to the finished preserve.
- English walnuts
- Add crunch and a rich, nutty flavor that contrasts with the soft fruit.
- Oranges
- Add acidity and citrus aroma, brightening the sweetness and supporting the set.
The step that matters
Boil the mixture for one hour, stirring occasionally. Sugar and fruit must be cooked long enough to concentrate and thicken. Stirring prevents the sugars from scorching on the bottom of the pot, which would give a burnt taste.
Swap the walnut
How well each one fits the dish's main ingredients (plum, sugar, raisin, orange):
- Almondfits better
- Chestnutfits better
- Pistachiofits better
- Walnutthe original
Fit is the average pairing score against plum, sugar, raisin, orange. Candidates are from the same food group and used in at least 100 recipes.
