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 Syrup
Ingredients
Directions
Extract the juice
Bruise the currants slightly and place them in an earthen jar.
Cover the jar and place it in a saucepan of cold water.
Heat the saucepan and let the fruit simmer gently until the juice flows freely.
Strain the juice if necessary and leave it in a cool place until the next day.
Pour off the clear juice, leaving any sediment behind.
Make the syrup
Weigh the juice and add an equal weight of sugar broken into small pieces.
Simmer the mixture, stirring to prevent the sugar from sticking, but do not let it boil.
Remove any scum that rises and once it stops, pour the syrup into an earthen jar to cool.
Bottle and store
After 12 hours, transfer the syrup into small dry bottles, cork, seal, and store 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 tart acidity that balances the sugar.
- White currants
- Add fruit juice and a milder, lighter tartness to the syrup.
- Sugar
- Adds sweetness and, as it dissolves in the juice, thickens the syrup and helps it keep.
The step that matters
Do not let the syrup boil. Simmering gently dissolves the sugar without caramelising it or driving off too much water. Stirring keeps sugar from scorching on the base of the pan, which would give a burnt taste.
