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 Cream 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
Preheat oven to 350°F (175°C).
Mix flour and cold water.
Divide batter into 2 greased cake pans.
Bake until golden brown.
Make the custard
In a saucepan, heat milk until almost boiling.
In a bowl, mix cornstarch with a little cold milk until smooth.
Add cornstarch mixture to hot milk, stirring constantly.
Beat eggs and sugar together.
Add beaten eggs and sugar to milk mixture.
Cook until thick enough to drop from a spoon.
Remove custard from heat.
Stir in melted butter.
Let custard cool.
Add vanilla to cooled custard.
Assemble
Once cakes are cool, split them.
Spread cream filling between layers.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Eggs
- Bind the custard and help it thicken and set when cooked.
- Cornstarch
- Thickens the milk mixture into a smooth, sliceable cream filling.
- Milk
- Forms the base of the custard and adds richness and body.
- Butter
- Adds fat for richness and a smooth, tender texture in the filling.
- Sugar
- Sweetens the custard and helps browning in the cake.
The step that matters
Cook the custard until thick. Cornstarch thickens only when the mixture reaches a full simmer and is stirred constantly. Stopping too early leaves a thin filling, while overcooking can scorch the milk or break the custard.
Swap the vanilla
How well each one fits the dish's main ingredients (flour, milk, egg, sugar, butter):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against flour, milk, egg, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
