Why it works: Butter and nutmeg are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 24,377 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. 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
Preheat the oven to 350°F (175°C).
Line a pie tin with the crust.
Bake until lightly golden.
Make the custard
In a saucepan, combine stewed apples, egg yolks, sugar, butter, and nutmeg.
Cook the mixture until thick.
Pour the mixture into the baked crust.
Top and brown
Beat the egg whites until stiff.
Gradually add 2 teaspoons of sugar to the egg whites.
Spread the meringue over the pie filling.
Brown the pie in the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set when heated, giving the filling its body.
- Sugar
- Sweetens the filling and helps stabilise the whipped egg white meringue.
- Butter
- Adds richness and a smooth, tender texture to the filling.
- Pie crust
- Forms the structure that holds the custard and meringue.
- Nutmeg
- Adds warm aroma that complements the apples and custard.
The step that matters
Cook the mixture until thick. Egg yolks thicken as their proteins set with heat, but too much heat makes them curdle and turn grainy. Cook gently and stop once the mixture coats a spoon.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, butter):
- Cinnamonfits about as well
- Nutmegthe original
- Capersfits less well
- Parsleyfits less well
Fit is the average pairing score against egg, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
