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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
Dissolve the chocolate in a little milk.
Stir the mixture into the boiling water.
Boil for 3 minutes.
Beat in the yolks of all the eggs and the whites of 3 eggs when nearly cold.
Stir the mixture into the milk, then season.
Bake and serve
Pour into pie shells.
When the custard is set but not more than half done, spread the whipped egg whites mixed with 2 tablespoons of sugar over it.
Bake in a 400°F oven until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard as they set, and whipped whites form the light topping.
- Milk
- Provides liquid and a creamy body for the custard.
- Baker's chocolate
- Supplies the chocolate flavor and the dark color of the custard.
- White sugar
- Sweetens the custard and helps the whipped whites hold their shape.
The step that matters
Spreading the egg-white topping. The whites should go on once the custard has set but is not fully baked. Egg proteins set with heat, so adding the topping too early can let it sink, while baking the custard too long can make it weep or curdle.
