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 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 cake batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Add the milk and eggs, mixing well.
Gradually stir in the flour and baking powder until combined.
Divide the batter in half and mix chocolate into one half.
Bake the layers
Pour the chocolate batter into one layer and the plain batter into another.
Bake the layers until a toothpick comes out clean.
Make the filling
Heat 1 pint of milk in a saucepan.
Mix sugar and corn starch in a separate bowl, then add to the hot milk.
Stir constantly until thickened, then add vanilla to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air, giving the cake a light, tender crumb.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Flour
- Forms the main structure of the cake once baked.
- Baking powder
- Releases gas in the batter, helping the layers rise.
- Chocolate
- Adds chocolate flavor and color to one of the cake layers.
- Corn starch
- Thickens the hot milk into a custard-like filling as it heats.
The step that matters
Stir the filling constantly until thickened. Corn starch granules swell and thicken liquid only when heated while stirred; stopping early leaves a thin filling, and letting it sit still can scorch or clump it on the bottom of the pan.
