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 Cheese Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the lemon filling
Beat the butter and sugar together until creamy.
Add 3 whole eggs, the juice, and grated rind of the lemons.
Cook the mixture in a granite saucepan until it thickens to the consistency of honey.
Remove from heat and store in jars until ready to use.
Assemble and bake
When ready, make a puff pastry and roll it out.
Place the pastry in patty pans and fill with the lemon mixture.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and fat, giving the filling a smooth, creamy body.
- Sugar
- Sweetens the filling and helps it turn creamy when beaten with the butter.
- Eggs
- Thicken the mixture as they cook and set it into a custard-like filling.
- Lemons
- Provide acidity and bright aroma from the juice and grated rind.
The step that matters
Cooking the lemon mixture until it thickens. Egg proteins set as they heat, so the mixture thickens gradually. If it gets too hot or cooks too fast, the eggs can scramble or curdle, leaving a grainy texture instead of a smooth, honey-like filling.
Swap the lemon
How well each one fits the dish's main ingredients (butter, sugar, egg):
- Vanillafits better
- Lemonthe original
- Raisinfits about as well
- Figfits about as well
Fit is the average pairing score against butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
