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 Cream Pie
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Make the filling
Combine milk, chocolate (or cocoa), sugar, egg yolks, cornstarch, and vanilla in a saucepan.
Cook until thick enough to pile.
Prepare the crust
Prepare a single pie crust by rolling dough on the outside of an inverted pie tin dusted with flour.
Bake for 5 minutes, then remove and place in the pie tin.
Bake and top
Pour the filling into the crust.
Bake in a hot oven (400°F / 200°C) until the filling just bubbles.
Beat the egg whites until stiff, then mix in 2 to 3 tablespoons sugar.
Spread over the pie.
Return to the oven until the meringue is delicately browned on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness to the chocolate filling.
- Cornstarch
- Thickens the milk mixture so the filling sets firm enough to slice.
- Egg whites
- Whipped into a stiff foam that forms the meringue topping.
- Chocolate
- Provides the chocolate flavor and color of the filling.
- Milk
- Forms the liquid base of the filling that cornstarch and yolks thicken.
The step that matters
Cook the filling until thick enough to pile. Cornstarch thickens only when the mixture reaches a full boil and holds it, so undercooked filling stays runny and will not set when cooled.
