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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Scald the milk and let it cool.
Grate the sweet apples.
Line a pie dish with the rich crust.
Make the custard
In a bowl, combine powdered sugar, beaten eggs, milk, and grated nutmeg.
Pour the custard mixture into the crust.
Bake and serve
Bake at 350°F (175°C) for 30 minutes.
Let it cool before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard into a firm, sliceable texture as they cook.
- Milk
- Forms the liquid base of the custard, giving it body and moisture.
- Powdered sugar
- Adds sweetness and dissolves smoothly into the liquid custard.
- Nutmeg
- Adds warm, aromatic flavour to the custard.
- Sweet apples
- Add fruit flavour and natural sweetness to the filling.
The step that matters
Let it cool before serving. Egg custard keeps setting as it cools, so cutting it too early can leave it runny. Baking too long can make it curdle or weep, so it should be taken out while the centre still wobbles slightly.
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.
