Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Apple Pie
Ingredients
Directions
Assemble the pie
Line a pie plate with pastry and fill it with sliced apples.
Sprinkle sugar and spice over the apples, then dot with bits of butter.
If the apples are not juicy, add a little water.
Cover with pastry and bake until golden.
Make the custard
In a double boiler, heat the milk until boiling.
Blend the egg yolks with cornstarch and a little milk, then add to the boiling milk.
Remove from heat and flavor with vanilla.
Serve
Serve each slice of pie with a scoop of vanilla ice cream on top.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pastry for pie crust
- Forms the enclosing shell that holds the filling while the pie bakes.
- Sliced apples
- Provide the main filling, softening as they bake and releasing juice.
- Butter
- Adds richness and fat that carries flavor and helps the filling taste rounded.
- Egg yolks
- Thicken the custard as they set when heated and add richness.
- Cornstarch
- Thickens the milk mixture into a smooth custard as it heats and gelatinises.
- Milk
- Forms the base of the custard, giving it body and a creamy texture.
The step that matters
Add the egg yolk mixture to the boiling milk. Egg yolks can scramble if overheated or added too quickly. Blending them with cornstarch and a little milk first helps them mix in smoothly, and the starch lets the custard thicken without curdling.
Swap the apple
How well each one fits the dish's main ingredients (sugar, butter, milk, egg, vanilla, cream):
- Strawberryfits better
- Coconutfits better
- Figfits better
- Applethe original
Fit is the average pairing score against sugar, butter, milk, egg, vanilla, cream. Candidates are from the same food group and used in at least 100 recipes.
