Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Marble Chocolate 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.
Prepare the batters
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter. Slowly add the milk, then mix in the flour sifted with baking powder. Fold in the beaten egg whites until well combined.
For the dark part, cream together the sugar and butter. Add the egg yolks and milk, then mix in the flour and baking powder. Stir in the grated chocolate.
Marble and bake
In a prepared pan, alternate spoonfuls of the white and dark batter.
Bake until a toothpick inserted comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites give the cake lift and an airy, tender crumb.
- Butter
- Creamed with sugar, it adds richness and a tender texture.
- Flour
- Forms the cake's structure once mixed with the liquids and leavening.
- Baking powder
- Releases gas during baking so the cake rises and stays light.
- Grated chocolate
- Adds deep chocolate flavor and contrasts the pale batter in the marble pattern.
The step that matters
Folding in the beaten egg whites. Folding gently preserves the air whipped into the whites; stirring or deflating them makes the cake dense and flat.
