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 ↓
French Chocolate Cake
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 batter
Preheat the oven to 350°F (175°C).
Beat the egg whites in a bowl until stiff.
Cream together the sugar and butter in another bowl.
Add the egg yolks to the creamed mixture and mix well.
Stir in the milk.
Fold in the beaten egg whites.
Sift together the flour and baking powder.
Add the sifted flour and baking powder to the mixture.
Make the layers
Use the yolks for the chocolate layer.
Mix in the grated chocolate.
Pour the batter into layers, alternating light and dark.
Bake until a toothpick comes out clean.
Make the custard and assemble
Combine the eggs, milk, sugar, and flour in a saucepan for the custard.
Cook over low heat until thickened.
Cool the custard and flavor with vanilla.
Spread the custard between the layers and on top of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten until stiff and folded in, they trap air and give the cake its light structure.
- Butter
- Creamed with sugar, it adds richness and tenderness to the crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the layers rise.
- Grated chocolate
- Gives the dark layer its chocolate flavor and color.
- Eggs
- Thicken the custard as they cook, setting it into a smooth filling.
The step that matters
Cook the custard over low heat until thickened. Egg proteins set as they heat, so high heat can scramble the eggs and leave lumps. Gentle heat, with steady stirring, gives a smooth custard.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
