Why it works: Black currant and red currant share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 72 recipes. Both carry isoamyl acetate, which smells banana, pear. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black currants
- Provide the fruit juice and natural pectin that let the jelly set.
- Sugar
- Sweetens the jelly and helps it set firm when boiled with the juice.
The step that matters
Boil the juice and sugar. The mixture must reach a full, sustained boil so enough water evaporates and the sugar and pectin can gel. Underboiling leaves a runny jelly that may not set.
Swap the red currant
The recipe marks red currant as optional. How well each one fits the dish's main ingredients (black currant, sugar):
- Vanillafits better
- Red currantthe original
- Blueberryfits less well
- Raspberryfits less well
Fit is the average pairing score against black currant, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
