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 ↓
Chocolate 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 the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the egg yolks and milk, mixing well.
In a separate bowl, combine the flour and baking powder, then add to the mixture.
Bake and fill
Divide the batter between two pie plates and bake until golden.
For the filling, beat the egg whites until stiff, then gradually add the sugar.
Fold in the grated chocolate and vanilla.
Once the pies are cool, spread the filling between the layers and on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the batter and help bind it, while whipped whites give the filling its light, airy structure.
- Butter
- Creamed with sugar, it adds richness and a tender crumb to the batter.
- Flour
- Provides the structure that holds the pie layers together.
- Baking powder
- Releases gas during baking so the layers rise and become lighter.
- Sugar
- Sweetens the batter and stabilizes the whipped egg white filling.
The step that matters
Beating the egg whites until stiff, then adding the sugar gradually. Egg whites whip best when clean and free of fat or yolk. Adding sugar gradually helps stabilize the foam, so the filling holds its volume instead of weeping or collapsing.
