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
Make the filling
Heat the milk, sugar, and chocolate together in a saucepan.
Mix the cornstarch with a little cold milk, then add it to the saucepan.
Stir in the beaten egg yolks and let the mixture come to a boil.
Bake and assemble

Pour the chocolate cream into the baked pie crust.
Make a meringue with the two egg whites and spread it on top of the pie.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the chocolate cream filling.
- Egg yolks
- Enrich the filling and help thicken it as it cooks.
- Sugar
- Sweetens the filling and balances the bitterness of the chocolate.
- Cornstarch
- Thickens the milk mixture into a smooth, sliceable cream when boiled.
- Grated chocolate
- Gives the filling its chocolate flavor and color.
The step that matters
Stir in the beaten egg yolks and let the mixture come to a boil. Egg yolks can curdle or scramble if added to hot liquid too quickly. Tempering them with hot mixture first and stirring constantly keeps the filling smooth, and the cornstarch needs a full boil to reach its full thickening power.
