Why it works: Red currant and white currant share more aroma than cooks usually use. They rank in the top 8% of all ingredient pairs, and cooks put them together in 4 recipes. Both carry isoamyl acetate, which smells banana, pear. The science ↓
Currant Jelly
Ingredients
Directions
Prepare the fruit
Pick over the currants without removing the stems, then wash and drain them.
Mash a few currants in the bottom of a preserving kettle using a wooden potato masher, and continue until all berries are used.
Cook the currants slowly until they look white.
Extract the juice
Strain the mixture through a coarse strainer, then allow the juice to drop through a double thickness of cheesecloth or a jelly bag.
Make the jelly
Measure the juice, bring it to a boil, and boil for five minutes.
Add an equal measure of heated sugar, boil for three minutes, skim off any foam, and pour into jars.
Set and store
Place the jars in a sunny window and let them stand for twenty-four hours.
Cover the jars and keep them in a cool, dry place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red currants
- Provide the main fruit flavour and the natural pectin and acid that help the jelly set.
- White currants
- Add tartness and fruit flavour, along with pectin and acid for setting.
- Granulated sugar
- Sweetens the jelly and helps it set into a firm, spreadable gel.
The step that matters
Boiling the juice before adding sugar. Boiling the juice first concentrates it and activates the natural pectin. Adding the sugar after that lets the jelly gel properly. Too little boiling can leave the jelly runny.
Swap the white currant
How well each one fits the dish's main ingredients (red currant, sugar):
- Raspberryfits better
- Vanillafits better
- Blueberryfits better
- White currantthe original
Fit is the average pairing score against red currant, sugar. Candidates are from the same food group and used in at least 100 recipes.
