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 ↓
Currant, Cherry, and Raspberry Jam
Ingredients
Directions
Prepare the fruit
Pick and stone the cherries.
In a pan, combine the cherries with ½ cup red currant juice and boil for about 20 minutes.
Make the jam
Add the black currants and raspberries along with the remaining red currant juice.
Once the fruit breaks down, add 1 pound of sugar for every pint of fruit and juice.
Boil until the jam reaches the desired consistency, skimming carefully.
Test the jam to ensure it sets properly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cherries
- Provide sweet-tart flavor and body as they soften into the jam.
- Black currants
- Add tartness and natural pectin to help the jam set.
- Raspberries
- Contribute aroma and fruity flavor, breaking down to thicken the mixture.
- Red currant juice
- Adds liquid to start the cooking and brightens the jam with acidity.
- Sugar
- Sweetens the jam and helps it gel as it thickens.
The step that matters
Boiling until the jam reaches the desired consistency. Sugar, fruit acid and pectin set together only within a narrow range of cooking. Stopping too early leaves the jam runny, while boiling too long makes it stiff and can scorch the sugar. Testing the set guards against both.
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.
