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 a very sweet apple sauce until no lumps remain.
Beat the eggs until light and mix with the apple sauce and milk.
Prepare pie crusts in pie plates.
Bake
Fill the crusts with the custard mixture and bake immediately without an upper crust at 350°F (175°C).

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.
- Fresh milk
- Adds moisture and richness, helping the custard stay tender rather than dry.
- Sweet apple sauce
- Provides the apple flavor, sweetness, and moisture that forms the body of the filling.
The step that matters
Bake immediately after filling the crusts. The custard mixture begins to separate and lose its airy texture if it waits, and eggs set best when heated promptly and evenly, so the filled pies should go into the oven right away.
Swap the apple
How well each one fits the dish's main ingredients (sauce, egg, milk):
- Vanillafits better
- Coconutfits better
- Figfits better
- Applethe original
Fit is the average pairing score against sauce, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
