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 Cheesecakes
Ingredients
Directions
Make the filling
In a saucepan, combine the sugar, butter, beaten eggs, lemon juice, and grated lemon rind.
Simmer the mixture, stirring constantly, until it thickens to a consistency like stiff honey.
Store and serve
Pour the mixture into jars and let it cool.
Seal the jars tightly; it will keep for three months or more.
To serve, spoon the mixture into patty pans and chill.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken the filling as they cook, giving it a rich, custard-like body.
- Butter
- Adds fat for a smooth, rich texture and helps the curd feel silky on the palate.
- Sugar
- Sweetens the filling and helps balance the sharpness of the lemon juice.
- Lemon juice
- Provides acidity and bright flavour, and helps thicken the mixture as it cooks with the eggs.
- Lemon rind
- Contributes aromatic lemon oils for fragrance and deeper citrus flavour.
The step that matters
Simmering until stiff honey consistency. Eggs thicken as their proteins set with gentle heat, but overheating can curdle them. Stirring constantly and stopping at the right thickness keeps the filling smooth.
