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 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the apple filling
Peel, core, and slice the apples.
Place them in a saucepan with the sugar and 1 tablespoon of water; simmer gently until tender.
Rub the apples through a fine sieve.
Return the apple pulp to the saucepan, add the lemon juice and finely grated lemon rind, and reheat.
Stir in the yolks of 3 eggs and the white of 1 egg, and cook until the mixture thickens.
Assemble and bake
Line patty pans with partially baked short crust, fill with the apple mixture, and cover lightly with stiffly whipped sweetened egg white.
Bake in a moderate oven at 350°F (175°C) for about 15 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 their pectin helps the pulp thicken when cooked down.
- Eggs
- Yolks thicken the apple mixture as they cook, and whipped white forms a light topping that sets in the oven.
- Butter
- Adds richness and fat to the dish, giving a softer, more tender texture.
- Sugar
- Sweetens the apples and helps them stew to a smooth pulp.
The step that matters
Cooking the egg yolks into the apple mixture. Egg yolks thicken when heated, but if the mixture gets too hot or boils, the eggs can scramble and turn grainy. Cook gently and stir until it just thickens.
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.
