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 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the custard
Combine grated chocolate and boiling water in a saucepan; let simmer for a few minutes.
Whisk egg yolks, cornstarch, and sugar together in a separate bowl.
Gradually add the chocolate mixture to the egg mixture, stirring constantly until it thickens like custard.
Flavor the custard to taste, then pour it into a pre-baked pie crust.
Top and bake
Beat egg whites with a little sugar until stiff peaks form, then spread over the chocolate filling.
Brown the meringue lightly in a preheated oven at 350°F (175°C).

What each ingredient does
- Grated chocolate
- Provides the chocolate flavor and color of the filling.
- Egg yolks
- Thicken the custard as they heat, giving it a rich, creamy set.
- Cornstarch
- Thickens the chocolate mixture so it holds its shape when sliced.
- Sugar
- Sweetens the filling and helps the egg whites form a stable meringue.
- Egg whites
- Whip into a foam that forms the meringue topping and sets when baked.
The step that matters
Stirring the chocolate into the egg mixture. Adding hot liquid too fast or stopping the stirring can scramble the egg yolks. Constant stirring keeps the custard smooth while the cornstarch thickens it.
