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 main flavor and most of the body of the filling.
- Sugar
- Sweetens the fruit and helps the mixture thicken and set as it cooks.
- Red currant juice
- Adds liquid and tartness, balancing the sweetness of the sugar.
The step that matters
Skimming during the boil. Foam forms on the surface as the fruit and sugar boil. Skimming it off keeps the filling clear and removes bits that could cloud or spoil its texture.
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.
