Why it works: Lemon and red currant 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 jelly
Combine water, sugar, gelatin, and lemon rind in a pan and stir until dissolved.
Add lemon juice, claret, and red currant jelly.
Whisk egg whites to a froth, crush the shells, and add them to the mixture. Whisk everything together and let it simmer for 5 minutes undisturbed.
Strain the mixture through a hot jelly bag.
Set
Do not use a metal mold for this jelly, as it will lose its color.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites and shells
- Clarify the liquid by collecting cloudy particles as it simmers, leaving the jelly clear.
- Leaf gelatine
- Sets the liquid into a firm, sliceable jelly as it cools.
- Claret
- Gives the jelly its red wine flavor and deep color.
- Loaf sugar
- Sweetens the jelly and balances the lemon juice's acidity.
The step that matters
Simmer undisturbed after adding the egg whites. Egg whites must be left to coagulate without stirring so they trap impurities and rise as a crust. Stirring breaks the crust and cloudies the jelly, so the clear straining step fails.
Swap the red currant
How well each one fits the dish's main ingredients (lemon, sugar, egg):
- Orangefits better
- Vanillafits better
- Limefits better
- Red currantthe original
Fit is the average pairing score against lemon, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
