Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Chocolate Cream Pie
Ingredients
Directions
Make the filling
In a saucepan, combine milk, sugar, cocoa powder, cornstarch, and salt.
Cook over medium heat, stirring constantly until thickened.
In a small bowl, whisk egg yolks, then gradually add a bit of the hot mixture to temper the eggs.
Stir the egg mixture back into the saucepan and cook for 2 more minutes.
Remove from heat and stir in butter and vanilla.
Assemble and serve
Pour filling into the pre-baked pie crust and let cool.
Top with whipped cream before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the filling and add richness and a smooth, custard-like texture.
- Cornstarch
- Thickens the milk mixture as it heats, giving the filling body that sets when cooled.
- Cocoa powder
- Provides the chocolate flavor and deep color of the filling.
- Butter
- Adds fat for a silky mouthfeel and a glossy finish to the filling.
- Milk
- Forms the liquid base that the starch and yolks thicken into a custard.
The step that matters
Tempering the egg yolks. Adding hot mixture to the yolks gradually, while whisking, warms them gently. Dumping them into hot liquid can scramble the eggs into lumps instead of a smooth filling.
