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 ↓
Trench 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 and weigh the juice.
Make the jelly
For every 4 lbs of juice, break 3 lbs of sugar into large lumps and dip them in cold water.
Boil the sugar until it forms a thick syrup, stirring constantly until it falls in large white masses from the skimmer.
Pour the currant juice into the syrup and boil quickly for 5 minutes.
Skim off any scum and pour the jelly into jars or warm glasses.
Set the jars in a cool place to set.

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 the pectin that lets the jelly set.
- White currants
- Add juice and mild flavour while contributing to the jelly's clear, pale colour.
- Sugar
- Sweetens the jelly and, with the acid and pectin, helps it set firm.
The step that matters
Boiling the sugar to a thick syrup. Sugar must be cooked until it reaches a thick syrup stage before the juice is added. Undercooked syrup leaves the jelly runny, while overcooking can make it grainy or caramelised.
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.
