Why it works: Apple and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,501 recipes. Both carry beta-damascenone, which smells apple, rose. 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).
Place the halved apples in the pie crust.
Make the topping
In a bowl, mix the sugar, butter, and flour until well combined.
Spread the mixture over the apples.
Bake and serve
Bake until the top is brown and the apples are tender.
Drizzle vanilla extract over the pie before serving warm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the fruit base and tender texture once baked.
- Sugar
- Adds sweetness and helps the top brown as it bakes.
- Butter
- Adds richness and fat, giving the topping a tender, moist texture.
- All-purpose flour
- Thickens the mixture so it sets rather than running out.

Fit is the average pairing score against sugar, butter, flour, vanilla. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
