Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crab apples
- Provide the fruit base and natural pectin that help the preserve set and thicken.
- Brown sugar
- Adds sweetness and body, and helps the preserve thicken as it cooks down.
- Ground cloves
- Contribute a warm, strong aroma that defines the spiced flavour.
- Black pepper
- Adds a mild, sharp warmth that balances the sweetness.
The step that matters
Cook gently for 1.5 hours. Sugar-rich fruit can scorch on the bottom of the kettle, leaving a burnt taste. Gentle heat lets water evaporate slowly, so the purée thickens evenly without darkening or sticking.
Swap the apple
How well each one fits the dish's main ingredients (crab, pepper, sugar, clove):
- Lemonfits better
- Limefits better
- Quincefits about as well
- Applethe original
Fit is the average pairing score against crab, pepper, sugar, clove. Candidates are from the same food group and used in at least 100 recipes.
