Why it works: Chocolate and sugar are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Chocolate Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the crust
Preheat the oven to 400°F (200°C).
Prick the pie crust well with a fork on both sides and the bottom.
Bake the crust until lightly golden.
Make the filling
In a saucepan, combine milk or water, egg yolks, cornstarch, grated chocolate, and sugar.
Boil the mixture until thick, then pour it into the baked crust.
Top and bake
Whip the egg whites to make meringue and spread it over the filling.
Bake the pie until the meringue is 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 to the custard.
- Cornstarch
- Thickens the milk mixture as it boils, giving the filling body.
- Egg whites
- Whipped into foam to form the airy meringue topping.
- Grated chocolate
- Provides the chocolate flavour and dark colour of the filling.
- Sugar
- Sweetens the filling and helps stabilise the whipped meringue.
- Milk
- Forms the liquid base of the filling that thickens when boiled.
The step that matters
Boil the filling until thick. Cornstarch only thickens fully when the mixture reaches a boil and is kept there briefly. Undercooked filling stays runny and will soak the crust and weep under the meringue.
