Why it works: Red currant and currant share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and cooks put them together in 57 recipes. Both carry isoamyl acetate, which smells banana, pear. The science ↓
French Currant Jelly
Ingredients
Directions
Prepare the juice
Mix the white and red currants in a pot over gentle heat until they release their juice.
Strain the mixture.
Weigh the juice.
Make the syrup
Break 3 lbs of sugar into large lumps.
Dip the sugar lumps in cold water.
Boil the sugar until it forms a thick syrup.
Stir the syrup constantly until it falls in thick masses from the skimmer.
Finish and set
Pour the currant juice into the syrup.
Boil quickly for 5 minutes, skimming off any scum.
Pour the jelly into jars or warm glasses.
Set the jars in a cool place.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red currants
- Provide most of the juice and natural pectin and acidity that help the jelly set.
- White currants
- Add juice and acidity to the jelly, contributing to its set and bright flavour.
- Sugar
- Sweetens the jelly and, with the fruit's pectin and acid, helps it gel.
The step that matters
Boiling the juice and sugar quickly. Boiling briskly for a short time drives off water and concentrates the sugar, pectin and acid so the jelly sets. Boiling too long can darken the flavour and make the set too stiff.
Swap the white currant
How well each one fits the dish's main ingredients (red currant, sugar, currant):
- Raspberryfits better
- White currantthe original
- Vanillafits about as well
- Plumfits about as well
Fit is the average pairing score against red currant, sugar, currant. Candidates are from the same food group and used in at least 100 recipes.
