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 Custard 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
Preheat the oven to 350°F (175°C).
Beat the egg yolks and whole egg together in a bowl.
Add the sugar, salt, and cocoa powder to the egg mixture.
Slowly add the hot milk while stirring, then strain the mixture.
Cool the mixture and add the vanilla extract.
Bake and top with meringue
Pour the mixture into a pie crust and bake until set.
Whip the egg whites until stiff peaks form and spread over the top as meringue.
Return to the oven and bake until the meringue is golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set, giving it a rich, smooth body.
- Whole egg
- Adds structure to the custard so it sets firm enough to slice.
- Sugar
- Sweetens the custard and helps keep the egg proteins tender.
- Cocoa powder
- Provides the chocolate flavor and deep color of the custard.
- Hot milk
- Forms the liquid base that the eggs thicken into a custard.
- Egg whites
- Whipped into stiff peaks to form the meringue topping that browns in the oven.
The step that matters
Adding the hot milk to the eggs. Pouring hot milk in slowly while stirring keeps the eggs from scrambling. Straining afterward removes any small cooked bits, so the custard stays smooth.
