Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. 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 filling
In a bowl, combine grated chocolate, egg yolks, vanilla, sugar, salt, cornstarch, and boiling water, then mix until smooth.
Pour into a pie crust.
Top and bake
Beat the egg whites with 1 tablespoon of sugar until stiff peaks form.
Spread the egg white mixture over the top of the pie.
Bake in a 350°F (175°C) oven until slightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the filling and add richness and color to the custard.
- Cornstarch
- Thickens the filling as it heats, giving it a sliceable body.
- Egg whites
- Whipped into a stiff meringue that forms a light topping that browns in the oven.
- Grated chocolate
- Provides the main chocolate flavor and deep color to the filling.
- Sugar
- Sweetens the filling and helps stabilize the whipped egg whites.
The step that matters
Beating the egg whites to stiff peaks. Egg whites need to be whipped until firm so the meringue holds its shape and does not weep or collapse in the oven. Under-beaten whites stay runny and slide off the filling, while over-beaten whites turn dry and grainy.
“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.
