Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grapes
- Provide the fruit base and pectin that help the marmalade thicken and set.
- Raisins
- Add body, natural sweetness and a deeper, chewy fruit texture.
- Sugar
- Adds sweetness, helps the mixture set into a jelly and preserves it.
- Oranges
- Add acidity and aroma, and their rind and pulp contribute pectin to the set.
The step that matters
Simmer gently until jelly-like. Sugar, fruit pectin and acid must be heated to the right point to gel. Undercooking leaves the marmalade runny, while boiling hard or too long can scorch the sugar, darken the colour and give a burnt flavour.
Swap the raisin
How well each one fits the dish's main ingredients (grape, sugar, orange):
- Vanillafits better
- Applefits better
- Figfits better
- Raisinthe original
Fit is the average pairing score against grape, sugar, orange. Candidates are from the same food group and used in at least 100 recipes.
