Why it works: Lemon and cinnamon match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 7,950 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Lemon Jelly
Ingredients
Directions
Prepare
Soak the gelatine in cold water for 10 minutes.
In a copper or porcelain-lined saucepan, combine the soaked gelatine, lemon rind, lemon juice, sherry, cinnamon stick, and sugar.
Heat over medium heat, stirring until the gelatine melts.
Clarify and set
In a bowl, whisk the egg whites slightly, then add to the saucepan and continue whisking until the mixture boils.
Remove the saucepan from heat, cover, and let it simmer slowly for 10 minutes.
Dip a flannel bag in tepid water and strain the mixture through it.
Pour the jelly into a mold and place it on ice until firm.
Serve
Serve the jelly turned out onto a crystal jelly dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Provides the gel structure that makes the jelly set firm when chilled.
- Egg whites
- Bind and draw out impurities as they heat, clarifying the jelly to a clear finish.
- Lemon juice
- Supplies the sharp acidity that gives the jelly its bright flavour.
- Sugar
- Adds sweetness that balances the sharpness of the lemon and sherry.
The step that matters
Straining through the flannel bag. Egg whites coagulate as the mixture heats and trap cloudy particles. Straining through a damp flannel bag lets the clear liquid pass while holding back the solids, so the jelly sets clear rather than cloudy.
Swap the lemon
How well each one fits the dish's main ingredients (cinnamon, sugar, sherry, egg):

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