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
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the custard
Heat 1 pint of milk in a saucepan.
Beat the yolks of 2 eggs.
Stir the beaten yolks into the milk.
Add ¼ teaspoon salt and 1 square of chocolate.
Allow the chocolate to dissolve.
Mix ½ cup sugar and 1 heaping tablespoon cornstarch together.
Stir the sugar‑cornstarch mixture into the hot milk.
Flavor with vanilla.
Pour the mixture into a baked pie crust.
Make the meringue and bake
Beat the egg whites to stiff peaks.
Gradually add 3 tablespoons sugar to the egg whites.
Spread the meringue over the pie.
Brown the pie in a 400°F (200°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the custard filling.
- Egg yolks
- Thicken the custard and add richness as they set with heat.
- Cornstarch
- Thickens the milk mixture into a smooth, sliceable filling.
- Chocolate
- Provides the chocolate flavor and color of the filling.
- Egg whites
- Whipped into foam to form the airy, stable meringue topping.
- Sugar
- Sweetens the filling and stabilizes the whipped egg white meringue.
The step that matters
Stir the sugar‑cornstarch mixture into the hot milk. Cornstarch clumps if added directly to hot liquid, so it should be mixed with sugar first and stirred in well. Once the filling is heated enough, the starch thickens it; without thorough stirring, lumps can form and the filling may stay thin.
