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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the apple sauce
Stew the tart apples until soft.
Strain the apples to make 1 cup of sauce.
Sweeten the sauce and season with nutmeg or mace.
Make the custard
Beat the eggs until light.
Mix the hot milk and a small amount of baking soda into the beaten eggs.
Let the sauce and custard cool.
Combine the cooled sauce with the custard.
Assemble and bake
Line a pie dish with the crust.
Brush the crust with egg white.
Add the filling to the crust.
Bake in a preheated oven at 400°F (200°C) without an upper crust.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tart apples
- Cook down into a soft sauce that gives the pie its moisture and tart flavor.
- Sugar
- Sweetens the apple sauce to balance the tartness of the apples.
- Eggs
- Set the custard as they cook, giving the filling its body.
- Hot milk
- Adds moisture and richness to the custard, softening its texture.
The step that matters
Let the sauce and custard cool before combining. Hot liquid poured into beaten eggs can scramble them and leave the custard grainy. Cooling both parts first keeps the egg proteins smooth so the filling sets evenly in the oven.
Swap the apple
How well each one fits the dish's main ingredients (sauce, sugar, nutmeg, egg, milk):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Applethe original
Fit is the average pairing score against sauce, sugar, nutmeg, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
