Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grapes
- Provide the main fruit flavour and the body of the preserve.
- Sugar
- Adds sweetness and, as it concentrates in boiling, helps the preserve thicken and keep.
- Orange
- Its juice adds acidity and its rind adds a bright citrus aroma.
- Raisins
- Add concentrated sweetness and a chewy texture.
- English walnuts
- Add crunch and a nutty flavour that contrasts with the soft fruit.
The step that matters
Boil for 20 minutes. Long boiling drives off water and concentrates the sugar and fruit pectin so the preserve thickens. Stopping early leaves it runny, and boiling too long can make it dark and sticky.
Swap the raisin
How well each one fits the dish's main ingredients (grape, orange, sugar, walnut):
- Figfits better
- Vanillafits better
- Pearfits better
- Raisinthe original
Fit is the average pairing score against grape, orange, sugar, walnut. Candidates are from the same food group and used in at least 100 recipes.
