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
- Provides tartness and bulk, with pectin-rich fruit helping the jam set.
- Black currants
- Add concentrated fruit flavor and natural pectin that help the jam thicken.
- Sugar
- Sweetens the jam, preserves it, and helps it thicken as it cooks.
The step that matters
Boiling slowly until thickened. Sugar and fruit pectin only set properly once enough water has evaporated and the mixture reaches the gel point. Stopping too early leaves a runny jam, while overcooking can scorch the sugar and dull the flavor.
Swap the black currant

- Vanillafits better
