Why it works: Apple and nutmeg are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 3,790 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Apple Custard Pie
Ingredients
Directions
Prepare the apples
Peel and core the sour apples.
Stew them in a small amount of water until soft.
Pass the cooked apples through a colander to create a smooth puree.
Make the filling
In a bowl, beat 3 eggs for each pie.
For every 3 pies, mix in ⅓ cup of butter and ⅓ cup of sugar.
Season the mixture with nutmeg.
Pour the filling into pie crusts.
Top and finish
Top with frosting, similar to lemon pie.
Return the pies to the oven for a few minutes to improve appearance.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour apples
- Provide the main fruit body and tart flavour of the filling once puréed.
- Eggs
- Set the smooth custard filling as they cook, giving it body and structure.
- Butter
- Adds richness and a tender, smooth mouthfeel to the custard.
- Sugar
- Sweetens the filling and contributes to browning on the surface.
- Nutmeg
- Adds a warm, aromatic spice note to the filling.
The step that matters
Pass the cooked apples through a colander. Cooked apples must be fully soft and pressed smooth; any lumps or fibrous bits will remain in the filling and spoil its silky texture. Egg-thickened custards also need gentle heat so the eggs set without curdling.
Swap the apple
How well each one fits the dish's main ingredients (egg, butter, sugar, nutmeg):
- Vanillafits better
- Lemonfits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against egg, butter, sugar, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
