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 ↓
Red Currant Jelly
Ingredients
Directions
Prepare the juice
Combine the red and white currants in a clean preserving pan.
Stir gently over medium heat until the juice flows freely.
Pour the mixture into a fine sieve and let it drain without pressure.

Weigh the juice.
Make the jelly
Boil the juice rapidly for 15 minutes.
For each pound of juice, add 8 ounces of coarsely powdered sugar.

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 pectin and tart acidity that give the jelly its body and flavour.
- White currants
- Add extra juice and pectin while keeping the jelly's colour lighter and its flavour mild.
- Coarsely powdered sugar
- Sweetens the jelly and helps it set by binding water and concentrating the pectin.
The step that matters
Boil the jelly for an additional 8 minutes after adding the sugar. Sugar must dissolve fully before the final boil; the jelly needs enough boiling to reach the concentration at which pectin and acid set. Undercooking leaves it runny, while overcooking can make it dull and tough.
Swap the white currant
How well each one fits the dish's main ingredients (red currant, sugar):
