Why it works: Lemon and butter 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
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Boil the rinds of the lemons until tender.
Pound the rinds in a mortar with sugar, egg yolks, butter, and curd until well mixed.
Bake
Line small pans with puff pastry.
Fill the pans half full with the mixture.
Bake in a 350°F (175°C) oven until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Yolks thicken as they set, giving the filling its firm, custard-like body.
- Butter
- Adds richness and a smooth, tender texture to the filling.
- Sugar
- Sweetens the filling and balances the sharp citrus flavour.
- Lemons
- Boiled rinds contribute bright lemon flavour and aroma to the filling.
The step that matters
Bake until set. Egg yolks set at moderate heat, and overbaking pushes them past that point, causing the filling to curdle, turn grainy, and weep liquid. Stop as soon as the centre is just set.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, butter):
- Vanillafits better
- Lemonthe original
- Raisinfits about as well
- Figfits about as well
Fit is the average pairing score against sugar, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
