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 moderate oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Pare, core, and boil enough apples to yield ½ lb. when cooked.
Add the sugar, melted butter, 2 egg yolks, and the grated rind and juice of the lemon, then stir the mixture well.
Bake
Line patty pans with puff pastry.
Fill the pastry with the mixture and bake for about 20 minutes at 400°F (200°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apple pulp
- Provides the main bulk and moist, tender body of the filling.
- Granulated sugar
- Adds sweetness and helps balance the tartness of the lemon and apples.
- Butter
- Adds richness and fat, giving the filling a smooth, tender texture.
- Eggs
- Yolks thicken and enrich the filling, helping it set as it bakes.
- Lemon
- Its juice and rind add acidity and aroma that brighten the apple flavor.
The step that matters
Stir the mixture well. Sugar, butter, egg yolks and fruit must be fully combined so the filling bakes evenly and sets smoothly rather than separating into pockets of fat or egg.
Swap the apple
How well each one fits the dish's main ingredients (sugar, butter, egg, lemon):
- Vanillafits better
- Orangefits better
- Raspberryfits better
- Applethe original
Fit is the average pairing score against sugar, butter, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
