Why it works: Milk and egg are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 88,785 recipes. Both carry 2-nonenal, which smells fatty, green. 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
In a saucepan, combine milk, cocoa powder, egg yolks, and cornstarch.
Cook over medium heat, stirring constantly, until thickened.
Pour the custard into the baked pie crust.
Top and bake
Beat the reserved egg white until stiff peaks form, then spread over the custard.
Brown the meringue in a 350°F (175°C) oven until golden.

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 custard that sets when cooked.
- Cocoa powder
- Provides the chocolate flavor and deep color of the filling.
- Egg yolks
- Thicken the custard and add richness as they cook.
- Egg white
- Whipped into stiff peaks to form the meringue topping.
- Cornstarch
- Thickens the custard by swelling in heat as it cooks.
The step that matters
Cook the custard until thickened. Cooking with constant stirring keeps the egg yolks and milk from scorching or lumping, and the starch needs to reach a full boil to thicken properly.
