Why it works: Vanilla and milk 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 ↓
Marble 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 batter
Cream the butter in a mixing bowl.
Gradually add the sugar and beat until light and fluffy.
Separate the eggs and beat the yolks in a separate bowl.
Add the beaten yolks to the butter and sugar mixture and beat again.
Stir in the milk and sift in the flour, mixing well.
Add the vanilla extract, then gently fold in the stiffly beaten egg whites and baking powder.
Marble and bake
Divide the batter in half; mix melted chocolate into one half.
In a greased pan, alternate spoonfuls of the light and dark batter.
Bake in a preheated oven at 350°F (175°C) for 45 to 60 minutes.
Finish
Ice with boiled chocolate icing if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the cake's structure once its proteins set during baking.
- Eggs
- Add structure, richness and moisture, and help the cake hold its rise.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Sugar
- Sweetens the cake and, creamed with butter, traps air for a lighter texture.
- Baking powder
- Releases gas during baking, making the batter rise and become light.
- Grated chocolate
- Provides the dark swirls and a deep chocolate flavour in one half of the batter.
The step that matters
Gently fold in the egg whites. Stiffly beaten egg whites hold air that gives the cake its lift. Vigorous stirring knocks that air out, leaving a dense, flat cake, so fold slowly with a spatula until just combined.
