Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black currant juice
- Provides the main flavour, plus the natural pectin and acid that help the jelly set.
- Sugar
- Sweetens the jelly and helps it set into a firm gel when boiled with the juice.
- Red currant juice
- Adds extra tartness and currant flavour.
The step that matters
Bringing the mixture to a boil. The juice, sugar and natural pectin must reach a full boil long enough to set. Boiling too briefly leaves the jelly runny, while boiling too long can make it stiff and dull in flavour.
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.
