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 Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the cake
Preheat the oven to 400°F (200°C).
In a bowl, combine the beaten egg whites and yolks with sugar, flour, milk, melted butter, baking powder, and vanilla. Mix until smooth and pour into cake pans.
Bake in the preheated oven until done, about 10-15 minutes.
Make the filling
For the filling, melt chocolate and butter together.
Stir in sugar.
Add the egg and slowly mix in hot water to avoid cooking the egg.
Add vanilla to the filling mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites and yolks provide structure and help the cake set as it bakes.
- Flour
- Forms the structure of the cake crumb as it sets in the oven.
- Sugar
- Sweetens the cake and adds tenderness to the crumb.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Chocolate
- Provides the chocolate flavour and richness of the filling.
- Milk
- Adds moisture and richness to the batter.
The step that matters
Add the egg and slowly mix in hot water. Adding hot water gradually and stirring constantly tempers the egg so it warms gently and thickens smoothly instead of scrambling into lumps.
