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 Cheesecake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Melt the butter and mix with sugar, lemon rind, and lemon juice.
Cook until the sugar dissolves and the mixture thickens to honey consistency.
Line, fill and bake
Line a pan with egg paste.
Pour the mixture into the lined pan.
Bake in a 400°F (200°C) oven until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken and set the filling, giving it a firm, custard-like structure when baked.
- Butter
- Adds fat for a rich, smooth texture and a soft mouthfeel.
- Loaf sugar
- Sweetens the filling and helps it thicken into a syrupy consistency when cooked.
- Lemon juice
- Provides the sharp acidity that gives the filling its tang.
- Lemon rind
- Supplies aromatic oils that give the filling its fresh lemon flavour.
The step that matters
Cooking the mixture to honey consistency. Gentle heat thickens the mixture as the sugar dissolves and the egg proteins begin to set. If it is overheated, the eggs can scramble or turn grainy, and if underheated it will not set properly when baked.
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.
