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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the filling and whites, beaten stiff, form a light topping that browns.
- Chocolate
- Provides the main chocolate flavor and body of the filling.
- Cornstarch
- Thickens the chocolate mixture so the filling sets smoothly.
- Sugar
- Sweetens the filling and helps stabilize the beaten egg whites.
- Milk
- Liquid that dissolves the chocolate and gives the filling its creamy moisture.
The step that matters
Pour the filling into the baked crust and bake until set. Egg yolks set when heated, but overbaking can make the custard weep or turn rubbery. Bake just until the center is set so the filling stays smooth and tender.
