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
Slice the apples and place them in a pan with butter, sugar, and lemon juice.
Cover and cook until soft.
Beat to a smooth pulp.
When cool, add cake crumbs and the egg yolk.
Fold in the beaten egg white.
Bake and serve
Line deep patty tins with pastry.
Fill the tins with the mixture.
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 and moisture of the filling, softening into a smooth pulp when cooked.
- Butter
- Adds fat for richness and a smoother, more tender texture.
- Sugar
- Adds sweetness and balances the tartness of the apples and lemon.
- Egg
- Binds the filling and helps it set as it bakes.
- Cake crumbs
- Absorb excess moisture and help thicken the filling.
- Lemon
- Adds acidity and fresh aroma that brighten the apple flavour.
The step that matters
Let the apple pulp cool before adding the egg yolk and white. Hot pulp can cook the raw egg yolk and white unevenly, causing lumps or scrambled bits instead of a smooth, evenly set filling.
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.
