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. The book gives no cooking times either; 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).
Cream the butter and sugar together until light and fluffy.
Add the sweet milk and mix well.
Sift together the flour and baking powder, then gradually add to the mixture.
In a separate bowl, beat the egg whites until stiff peaks form, then fold them into the batter.
Marble and bake
Take 1 cup of the batter and mix in the grated chocolate that has been wet with milk and flavored with vanilla.
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 for about 30-35 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
- Creams with sugar to trap air, giving the cake a light, tender crumb.
- Sugar
- Sweetens the cake and helps create a light texture when creamed with butter.
- Flour
- Forms the structure of the cake as the batter sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and becomes airy.
- Eggs
- Egg whites whipped to stiff peaks add lightness and help the cake rise and set.
- Grated chocolate
- Adds chocolate flavor and creates the dark marbled streaks through the white batter.
The step that matters
Folding in the egg whites. Whipped whites hold air that gives the cake its rise. Stirring them in vigorously deflates the foam, leaving a dense, flat cake, so fold gently with a spatula.
