Why it works: Butter and lemon are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 41,227 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Lemon Honey
Ingredients
Directions
Melt the butter in a saucepan.
Add the sugar and stir until combined.
In a bowl, beat the eggs and add them to the mixture, leaving out 2 egg whites.
Grate the rinds of the lemons and add them along with the lemon juice.
Simmer over low heat, stirring constantly, until the mixture thickens to a honey-like consistency. Be careful not to let it burn.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the mixture as they set during simmering, giving the custard its body.
- Butter
- Adds richness and a smooth, silky mouthfeel to the custard.
- Sugar
- Sweetens the custard and helps it thicken into a smooth, glossy texture.
- Lemon juice
- Adds acidity and bright citrus flavour that balances the sweetness.
- Lemon rinds
- Contribute aromatic lemon oils that add fragrance and depth of flavour.
The step that matters
Simmer over low heat, stirring constantly. Egg proteins set at moderate temperatures, so high heat or lack of stirring can scramble the eggs and make the custard grainy or burnt. Gentle, constant stirring keeps the mixture smooth as it thickens.
