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 Pies
Ingredients
Directions
Prepare the filling
Make the stewed apples very sweet and let them cool.
Beat the eggs until light, then mix the yolks with the cooled apples and season with nutmeg.
Gradually stir in the milk while beating constantly.
Add the beaten egg whites last.
Bake
Fill your pie crust with the mixture and bake without a top crust.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks and whites bind the custard and help it set as it bakes.
- Milk
- Provides liquid that gives the custard its soft, creamy body.
- Stewed apples
- Supply moisture and apple flavor that fills the custard.
- White sugar
- Sweetens the filling and balances the tartness of the apples.
The step that matters
Gradually stir in the milk while beating constantly. Adding milk slowly while beating keeps the egg proteins evenly dispersed, so the custard blends smoothly instead of curdling or forming lumps as it heats.
Swap the apple
How well each one fits the dish's main ingredients (sugar, egg, milk, nutmeg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against sugar, egg, milk, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
