Why it works: Cocoa and vanilla work together. They rank in the top 4% of all ingredient pairs, and cooks put them together in 357 recipes. Both carry sotolon, which smells curry, maple. 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
Beat the egg yolks and whole egg together.
Add the sugar, salt, and cocoa to the egg mixture.
Slowly add the hot milk.
Strain the mixture and let it cool.
Add vanilla for flavor.
Bake and top
Pour the mixture into a pie crust.
Bake at 350°F (175°C) until set.
Whip the egg whites to make meringue.
Spread the meringue 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
- Eggs
- Egg yolks and whole egg thicken the custard as they set during baking.
- Milk
- Provides the liquid base and moisture for the custard.
- Sugar
- Sweetens the custard and balances the bitterness of the cocoa.
- Cocoa
- Gives the custard its chocolate flavor and color.
- Egg whites
- Whipped into meringue, they form a light foam that tops the pie.
The step that matters
Slowly add the hot milk. Adding hot liquid to beaten eggs too quickly can scramble them. Pouring gradually while whisking tempers the eggs so the custard stays smooth and thickens evenly.
Swap the cocoa
How well each one fits the dish's main ingredients (milk, vanilla, egg, sugar):
- Almondfits about as well
- Chestnutfits about as well
- Cocoathe original
- Hazelnutfits about as well
Fit is the average pairing score against milk, vanilla, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
