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 ↓
Chocolate 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 together the butter and sugar.
Add the milk, flour, and baking powder, mixing well.
Fold in the egg whites last.
Make the chocolate batter
Take 1 cup of this mixture and mix in the grated chocolate and a little milk, adding vanilla for flavor.
Marble and bake
In a cake pan, pour a layer of the white batter.
Drop the chocolate batter in spots on top.
Pour the remaining white batter over the chocolate spots.
Bake at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness, and helps the cake stay moist.
- Sugar
- Sweetens the cake and helps it brown while baking.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Egg whites
- Add structure and lift to the batter when folded in last.
- Grated chocolate
- Provides the chocolate flavor and the dark marbled streaks.
The step that matters
Fold in the egg whites last. Folding gently keeps the air trapped in the egg whites, which helps the cake rise and stay light. Stirring vigorously deflates the foam and produces a dense cake.
