Why it works: Milk and apple 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 ↓
Apple Custard 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.
Prepare
Preheat your oven to 350°F (175°C).
Line your pie plate with the pie crust.
Slice the apples thinly and fill the pie plate halfway with them.
Make the custard and bake
In a bowl, whisk together the eggs, milk, sugar, and nutmeg or cinnamon.
Pour the custard mixture over the apples in the pie plate.
Bake until the custard is set and the crust is golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook, giving the filling its structure.
- Milk
- Forms the liquid base of the custard, adding moisture and softness.
- Apples
- Provide the fruit filling that the custard bakes over, adding moisture and flavor.
- Sugar
- Adds sweetness and helps the custard taste balanced.
The step that matters
Bake until the custard is set. Eggs thicken as they heat, but overbaking can make the custard curdle, weep liquid, or turn rubbery. Pull the pie when the center is just set and still slightly jiggles, since it keeps firming as it cools.
Swap the apple
How well each one fits the dish's main ingredients (egg, milk, sugar, nutmeg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against egg, milk, sugar, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
