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 flavour, natural pectin and acidity that give the jam its body and tang.
- Pounded loaf sugar
- Sweetens the jam and helps it set by binding water and thickening as it boils.
The step that matters
Boil the mixture and skim for 25 minutes. Boiling concentrates the sugar and fruit until the pectin and acid can set the jam. Skimming removes foam, which keeps the jam clear and prevents off flavours.
Swap the red currant
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.
