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
Extract 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
Dip the sugar lumps in cold water until nearly dissolved, then boil to a thick syrup.
Stir the syrup continuously until it falls in large, thick masses from the skimmer.
Pour in the currant juice and boil quickly for 5 minutes after the sugar dissolves.
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
- White currants
- Provide the bulk of the juice and tart fruit flavour for the jelly.
- Red currants
- Add pectin and acidity to help the juice gel with the sugar.
- Sugar
- Sweetens the jelly and helps it set firm when boiled with the juice.
The step that matters
Stir the syrup until it falls in thick masses. Sugar syrup must reach the right concentration before juice is added. Undercooked syrup leaves the jelly runny, while overcooking makes it stiff and grainy. Continuous stirring prevents scorching on the base of the pot.
