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 ↓
Apple Custard Pie. No. 1
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 the oven to 350°F (175°C).
Lay the pie crust in a pie plate.
Slice enough apples to half fill the pie plate.
Make the custard
In a bowl, whisk together the eggs, milk, sugar, and seasoning.
Pour the custard mixture over the apples.
Bake
Bake until the custard is set in the middle.

Apple and sugar barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Coagulate when heated, setting the milk custard so it holds its shape.
- Milk
- Forms the liquid base of the custard and, with the eggs, sets into a soft texture.
- Apples
- Provide the fruit filling and moisture that cooks down beneath the custard.
- Sugar
- Adds sweetness and helps balance the flavour of the custard.
The step that matters
Bake until the custard is set in the middle. Eggs keep setting as they cool, so underbaking leaves a runny centre, while overbaking can make the custard grainy or cause it to weep. Check the middle for a gentle wobble rather than a liquid slosh.
Swap the apple
How well each one fits the dish's main ingredients (egg, milk, sugar):
- Vanillafits better
- Figfits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against egg, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
