Why it works: Rhubarb and black currant share more aroma than cooks usually use. They rank in the top 6% of all ingredient pairs, and cooks put them together in 10 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb juice
- Provides the liquid base and natural tartness that balances the sugar.
- Sugar
- Sweetens the jam and, as it cooks down, helps it thicken and set.
- Black currants
- Supply the main fruit flavour, pectin and body for the jam.
The step that matters
Boil for 15 minutes or until the currants are tender. Boiling concentrates the sugar and fruit until the mixture reaches a set; stopping too early leaves the jam runny, while overcooking can darken and dull its flavour.
Swap the black currant
How well each one fits the dish's main ingredients (rhubarb, sugar):
- Vanillafits better
- Figfits better
- Quincefits better
- Black currantthe original
Fit is the average pairing score against rhubarb, sugar. Candidates are from the same food group and used in at least 100 recipes.
