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 Pie
Ingredients
Directions
Make the filling
In a bowl, mix sugar, flour, cornstarch, and salt.
Add beaten eggs to the dry mixture.
Pour the mixture into the scalded milk and cook over medium heat until thick.
Transfer to a double boiler and cook for an additional 15 minutes, stirring constantly.
Finish the pie
Let the filling cool, then pour it into a baked pie crust.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the filling as they set with heat and add richness.
- Cornstarch
- Thickens the milk mixture into a smooth, sliceable filling as it heats.
- Flour
- Adds additional thickening so the custard holds its body.
- Milk
- Forms the liquid base of the custard that thickens during cooking.
- Sugar
- Sweetens the filling and balances the bitterness of the chocolate.
- Chocolate
- Provides the main chocolate flavor and the filling's dark color.
The step that matters
Cook the filling until thick, stirring constantly in the double boiler. Starch thickens only when heated through, so the filling must be cooked long enough to set. Constant stirring keeps the starch and egg from scorching or lumping, and gentle heat stops the eggs from curdling.
