Why it works: Red currant and lemon work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 309 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓
Claret Jelly
Ingredients
Directions
Make the mixture
In a pan, combine water, sugar, gelatine, and lemon rind. Stir until dissolved.
Add lemon juice, claret, and red currant jelly.
Clarify and strain
Whisk the egg whites to a froth and crush the shells, then add to the mixture.
Simmer for 5 minutes without stirring, then strain through a hot jelly bag.
Set
Do not use a metal mold for this jelly to preserve its color.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leaf gelatine
- Sets the liquid into a firm jelly as it cools.
- Egg whites
- Bind to impurities as they heat, so straining leaves the jelly clear.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sugar.
- Loaf sugar
- Adds sweetness and helps give the jelly body.
- Claret
- Provides the main wine flavour and deep red colour.
- Red currant jelly
- Adds fruit flavour and extra gelling power from its natural pectin.
The step that matters
Simmer without stirring, then strain through a hot jelly bag. Egg whites coagulate and trap cloudy particles as they heat. Stirring breaks up this raft and lets impurities pass through, so the jelly stays clear when strained through a hot bag.
Swap the red currant
How well each one fits the dish's main ingredients (lemon, egg, sugar):
- Orangefits better

- Red currantthe original
Fit is the average pairing score against lemon, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
