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 filling
Combine grated chocolate, cornstarch, milk, sugar, egg yolks, and butter in a saucepan.
Stir together and cook over medium heat until thickened.
Make the meringue and bake
Beat the egg whites until soft peaks form.
Gradually add 1 tablespoon of sugar to the egg whites and continue beating until stiff peaks form.
Spread the meringue over the chocolate filling and bake in a 350°F (175°C) oven until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornstarch
- Thickens the milk and chocolate mixture as it cooks into a custard-like filling.
- Egg yolks
- Enrich and thicken the filling, adding richness and a smooth texture.
- Egg whites
- Whipped into a foam that forms the meringue topping, which sets and browns in the oven.
- Grated chocolate
- Provides the chocolate flavor and color of the filling.
- Sugar
- Sweetens the filling and, when beaten into the whites, stabilizes the meringue.
The step that matters
Cooking the filling until thickened. Cornstarch only thickens fully when the mixture reaches a simmer and is stirred constantly. Undercooked filling stays runny and may not hold its shape when the meringue is added and baked.
“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.
