Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate 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 filling
In a bowl, combine sugar, egg yolks, butter, flour, and a little cold water.
Add sweet milk and grated chocolate, then beat until well mixed.
Cook the mixture over medium heat until thickened.
Flavor with vanilla.
Pour into a pre-baked pie crust.
Make the meringue and bake
Beat egg whites to stiff peaks.
Gradually add sugar.
Spread the meringue over the pie.
Brown in a 350°F (175°C) oven.

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 and add richness and colour to the filling.
- Egg whites
- Whip into a stiff foam that forms the meringue topping.
- Flour
- Helps thicken the filling so it sets smoothly when cooked.
- Grated chocolate
- Gives the filling its chocolate flavour and dark colour.
- Sugar
- Sweetens the filling and stabilises the whipped egg white meringue.
The step that matters
Cook the filling until thickened. Egg yolks and flour thicken as the custard heats. Undercooking leaves the filling runny and unset, while overheating can curdle the eggs, so watch it closely over medium heat.
