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
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
Make the stewed apples very sweet and let them cool.
Make the custard
Beat the eggs until light and mix the yolks with the apples, seasoning with nutmeg.
Gradually stir in the milk while beating the mixture.
Fold in the beaten egg whites.
Bake
Fill your pie crust and bake uncovered at 350°F (175°C) until 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 and add richness and structure to the filling.
- Milk
- Provides the liquid base that the eggs set into a smooth, tender custard.
- Stewed apples
- Supply the fruit flavor and moisture that fill the pie.
- White sugar
- Sweetens the apples and adds to the custard's flavor.
The step that matters
Bake until set. Eggs set as their proteins coagulate with heat. Pulling the pie too early leaves a runny centre, while overbaking can make the custard weep or turn grainy.
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.
