Why it works: Sugar and chocolate 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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
In a saucepan, combine egg yolks, sugar, melted chocolate, cornstarch, and milk.
Cook over medium heat, stirring constantly, until thickened.
Pour the mixture into a prepared rich pie crust.
Top and bake
In a separate bowl, beat egg whites until stiff peaks form, then gradually add 2 tablespoons of sugar.
Spread the meringue over the chocolate filling.
Bake in a preheated oven at 350°F (175°C) until lightly browned.

Sugar and milk barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
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 filling and add richness as they set with heat.
- Cornstarch
- Thickens the milk and chocolate mixture into a sliceable filling when cooked.
- Egg whites
- Whipped into stiff peaks to form the meringue topping that browns in the oven.
- Melted chocolate
- Provides the chocolate flavour and some body to the filling.
- Sugar
- Sweetens the filling and, in the meringue, helps stabilise the whipped whites.
The step that matters
Cook the filling until thickened. Cornstarch only thickens fully once the mixture reaches a boil while stirred constantly; stopping early leaves a runny filling that will not set when cooled. Constant stirring prevents the yolks and milk from scorching or curdling on the bottom of the pan.
