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 ↓

Ingredients
Directions
Make the custard base
Melt the sugar in water over low heat.
Beat the egg yolks well.
Squeeze the lemon juice and scrape the rind into the sugar water.
Mix well, then stir in the egg yolks continuously.
Strain the mixture through a fine sieve.
Thicken and finish
Place the jug in a saucepan of boiling water, stirring until it thickens like custard.
Beat the egg whites to stiff peaks and fold into the mixture until light.
Pour into custard glasses and sprinkle with cinnamon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they heat and set, giving it a rich, smooth body.
- Egg whites
- Whipped to stiff peaks, they lighten the custard with trapped air.
- Lemon juice
- Adds sharp acidity that balances the sweetness of the sugar syrup.
- Sugar
- Sweetens the custard and balances the sharpness of the lemon.
The step that matters
Stirring the yolks into the warm syrup. Egg yolks scramble if they meet too much heat too fast. Adding them while stirring constantly and heating gently over water lets them thicken smoothly into custard instead of curdling.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, cinnamon):

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