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 says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare the apples
Quarter the apples and cook until half tender, sweetening to taste.
Cut the cooked apples into small pieces and place them in the bottom of the lined pie pan.
Make the custard
Line a pie pan with flaky pastry, treating the bottom with flour.
Beat the eggs until mixed, then combine with milk, sugar, and nutmeg.
Pour the mixture over the apples in the pie shell.
Bake
Bake in a hot oven (400 °F / 200 °C) for the first 10 minutes, then reduce the heat to moderate (350 °F / 175 °C) for the remainder of the time.
The pie is done when the custard is set.

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 and body.
- Milk
- Forms the liquid base of the custard, adding moisture and softness to the filling.
- Stewed apples
- Provide the fruit filling and moisture beneath the custard.
- Sugar
- Adds sweetness and helps balance the tartness of the apples.
The step that matters
Baking at the right temperature and stopping when the custard is set. Eggs set through gentle heat. A hot oven that is not reduced can overcook the custard, making it curdle or turn watery, so the pie should be checked for a set centre rather than just timed.
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.
