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 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
Combine apples, butter, sugar, and lemon juice in a pan, cover, and cook until soft.
Mash the cooked apples into a smooth pulp and let cool.
Mix in cake crumbs and egg yolk, then fold in the beaten egg white.
Bake
Line deep patty tins with pastry, fill with the apple mixture, and bake at 400°F (200°C) for 10 to 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the bulk of the filling and its tender, fruity body once cooked down.
- Egg
- Sets the filling as it bakes and gives it a light, custard-like structure.
- Egg yolk
- Adds richness and helps bind the filling while setting.
- Butter
- Adds fat for a smooth, rich texture and mouthfeel.
- Sugar
- Sweetens the filling and helps the apples cook to a soft pulp.
The step that matters
Folding in the beaten egg white. Folding, rather than stirring, keeps the air in the beaten egg white so the filling stays light. Overmixing knocks out that air and can leave the filling dense.
Swap the apple
How well each one fits the dish's main ingredients (butter, lemon, sugar, egg):
- Vanillafits better
- Orangefits better
- Raspberryfits better
- Applethe original
Fit is the average pairing score against butter, lemon, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
