Why it works: Apple and lemon are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 7,551 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Apple Cheesecakes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make the filling
Grate the apples and mix with melted butter and sugar.
Add the egg yolks, egg whites, lemon juice, and grated lemon rind; mix well.
Bake
Pour the mixture into a puff pastry shell.
Bake until set and golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide moisture and fruity flavour that bakes into the filling.
- Butter
- Adds richness and fat, giving the filling a smooth, tender texture.
- Sugar
- Adds sweetness and helps the filling brown in the oven.
- Egg yolks
- Enrich the filling and help it set into a custard-like texture.
- Egg whites
- Add structure as they set, helping the filling hold together when baked.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
The step that matters
Bake until set and golden brown. Eggs set through heat, so underbaking leaves a runny centre while overbaking can make the filling curdle, dry out, or toughen. Look for a firm centre and an even golden colour.
