Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. 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 saucepan, combine grated chocolate and hot water, stirring until melted.
Add cornstarch and brown sugar, mixing well.
Stir in beaten egg yolks, butter, and vanilla until smooth.
Pour the mixture into a pie crust.
Top and bake
Whip the egg whites until stiff peaks form and spread on top of the pie.
Brown the pie in a 350°F (175°C) oven until the meringue is golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated chocolate
- Provides the chocolate flavor and body of the filling as it melts into the hot water.
- Cornstarch
- Thickens the filling as it heats, giving it a sliceable, custard-like set.
- Egg yolks
- Add richness and help set the filling, thickening it with the cornstarch.
- Brown sugar
- Adds sweetness and a molasses note that deepens the chocolate flavor.
- Egg whites
- Whipped into stiff peaks to form a light meringue that browns on top.
The step that matters
Stir the filling smooth before baking. Melting the chocolate fully and stirring the yolks in well keeps the filling even. Cornstarch needs to be heated to thicken properly, so the filling sets rather than staying thin or lumpy.
