Why it works: Apple and milk are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 4,104 recipes. Both carry 4-heptenal, which smells creamy, biscuit. The science ↓
Green Apple Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
Stew the tender sour apples and press them through a sieve.
Add the egg yolks, milk, and sugar to the apple puree.
Pour the mixture into a pie crust and bake without an upper crust at 350°F (175°C).
Top with meringue
Beat the egg whites until stiff, then gradually add 3 tablespoons of sugar and 1 teaspoon of lemon juice.
Spread the meringue on the hot pie and return it to the oven until lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tender sour apples
- Provide the main body of the filling and its tart flavour.
- Egg yolks
- Thicken the apple filling as they set during baking.
- Egg whites
- Whip into a stiff foam that forms the light meringue topping.
- Sugar
- Sweetens the filling and helps the meringue become stable and glossy.
- Milk
- Adds moisture and softness to the custard-like filling.
The step that matters
Beat the egg whites until stiff. Egg whites must be fully whipped before sugar is added so they hold a stable foam. Under-beaten whites will weep or collapse in the oven, while the lemon juice helps stabilise the foam.
Swap the apple
How well each one fits the dish's main ingredients (egg, milk, sugar, lemon):
- Vanillafits better
- Orangefits better
- Figfits better
- Applethe original
Fit is the average pairing score against egg, milk, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
