Why it works: Lemon and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Port Wine Jelly
Ingredients
Directions
Make the jelly
Combine the sugar, port wine, and gelatine in a pan. Stir until dissolved.
Add the thinly pared rind and strained juice of the lemons, along with the whipped egg whites. Whisk well.
Simmer gently for 5 minutes without stirring.
Pour the mixture through a jelly bag rinsed in hot water.
Set and serve
Once cool, pour into a china mold to set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Port wine
- Provides the main flavor and liquid that the gelatine sets into a jelly.
- Egg whites
- Whipped whites help clarify the liquid as they coagulate and are strained out with the impurities.
- Gelatine
- Sets the liquid into a firm jelly as it cools.
- Lemons
- Add acidity and aroma from the juice and pared rind.
- Loaf sugar
- Sweetens the jelly and balances the acidity of the lemon and wine.
The step that matters
Simmer gently without stirring. Stirring can break up the egg white raft that forms as it heats, so it stays clumped and fails to clarify the liquid. Gentle simmering lets the whites collect impurities so the jelly strains clear.
Swap the lemon
How well each one fits the dish's main ingredients (port wine, egg, sugar):
- Figfits better
- Vanillafits better
- Pearfits about as well
- Lemonthe original
Fit is the average pairing score against port wine, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
