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
Make the chocolate base
Dissolve the chocolate in a little of the milk.
Stir the chocolate mixture into the boiling water and boil for 3 minutes.
Make the custard
Cool the mixture, then add the beaten egg yolks (reserve the whites of 3 eggs), vanilla, and remaining milk.
Pour the custard into pie dishes lined with crust.
Top and bake
When the custard is set but not more than half done, spread the beaten egg whites mixed with 2 tablespoons of sugar over the top.
Bake until the egg whites are lightly browned.
This can also be baked without crust in a pudding dish or cups set in boiling water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the main chocolate flavor and body to the filling.
- Eggs
- Thicken the custard as they set and add richness and structure.
- Milk
- Forms the liquid base of the custard and keeps it soft and smooth.
- Sugar
- Sweetens the custard and the topping and helps the egg whites brown.
The step that matters
Spreading the egg whites on a partly set custard. Egg custard sets with gentle heat, and if it is baked too long before the topping goes on, it can become firm, curdled or watery. Adding the meringue topping only once the custard is set but not fully cooked keeps the texture smooth and lets the whites brown evenly.
