Why it works: Vanilla and cocoa work together. They rank in the top 4% of all ingredient pairs, and cooks put them together in 357 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Marble Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the butter and sugar.
Add the milk and the yolks of the eggs, then mix in the vanilla.
Stir in the flour and baking powder.
In a separate bowl, beat the egg whites until stiff and fold them into the batter.
Take a portion of the batter and mix it with the cocoa.
Bake
In a greased pan, layer the white batter and then the cocoa batter on top.
Bake for about 30-40 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that makes the crumb tender and rich.
- Eggs
- Whites are beaten for lift and structure; yolks add richness and help bind the batter.
- Flour
- Provides the structure that sets the cake's crumb as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps create a soft, tender crumb.
- Cocoa
- Adds chocolate flavor and the darker marbled color to part of the batter.
The step that matters
Folding in the beaten egg whites. Stiff whites hold air that gives lift. Stirring them in vigorously knocks the air out, while gentle folding keeps the cake light.
Swap the cocoa
How well each one fits the dish's main ingredients (butter, sugar, milk, egg, flour, vanilla):
- Almondfits better
- Chestnutfits better
- Hazelnutfits about as well
- Cocoathe original
Fit is the average pairing score against butter, sugar, milk, egg, flour, vanilla. Candidates are from the same food group and used in at least 100 recipes.
