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 ↓
Marbled Chocolate 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar until light and fluffy.
Add the milk and mix well.
Sift the flour and baking powder, then mix until combined.
Gently fold in the egg whites.
Make the marbled cake
Take 1 cup of the batter and mix in the grated chocolate and a little milk to wet it, adding vanilla for flavor.
In a cake pan, pour a layer of the white batter, then drop spoonfuls of the chocolate batter in spots.
Pour the remaining white batter over the top and bake until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cake a light, tender crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas in the batter so the cake rises and becomes airy.
- Egg whites
- Folded in to add lift and structure to the batter.
- Grated chocolate
- Supplies the chocolate flavor and the dark swirls in the marbled batter.
The step that matters
Folding in the egg whites. Egg whites hold air that gives the cake its lift. Folding gently, rather than stirring hard, keeps that air in the batter so the cake stays light instead of dense.
