Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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.
Make the custard
Preheat the oven to 350°F (175°C).
Beat the egg yolks thoroughly, then stir in the sugar, chocolate, and cornstarch.
Add the milk and melted butter, mixing well.
Pour the mixture into a single pie crust and bake until the custard is set.
Top and brown
Beat the egg whites until stiff, adding 4 tablespoons of sugar to make the meringue.
Spread the meringue over the pie and return to the oven until lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard and whites whip into the meringue that tops the pie.
- Sugar
- Sweetens the filling and stabilizes the whipped egg whites in the meringue.
- Cornstarch
- Thickens the custard so it sets into a sliceable filling.
- Milk
- Provides the liquid base that the eggs and cornstarch set into a creamy custard.
- Chocolate
- Gives the filling its chocolate flavor and dark color.
- Butter
- Adds richness and a smoother, softer texture to the filling.
The step that matters
Beat the egg whites until stiff. Any trace of yolk or grease prevents the whites from whipping fully, so the meringue may stay soft or weep. Beating in the sugar gradually helps it hold its shape.
“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.
