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 says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream butter and sugar until light and fluffy.
Add sweet milk and mix well.
In a separate bowl, combine flour and baking powder, then add to the butter mixture.
Beat egg whites until stiff and fold them into the batter.
Marble and bake
Take 1 cup of the batter and mix in grated chocolate, wetting it with milk and adding vanilla.
In a greased cake pan, pour a layer of the white batter.
Drop spoonfuls of the chocolate batter onto the white batter in spots.
Top with the remaining white batter and bake until a toothpick comes out clean.
Finish
Once cooled, frost with chocolate icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender crumb and flavor.
- Sugar
- Creams with butter to hold air and adds sweetness and browning.
- Flour
- Provides the structure that sets the cake as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Eggs
- Egg whites whipped to stiff peaks add lift and an airy texture.
- Grated chocolate
- Provides the dark marbling and rich chocolate flavor in the cake.
The step that matters
Folding in the stiff egg whites. Whites beaten to stiff peaks trap air that makes the cake light. Stirring them in vigorously or too long deflates that foam, leaving a dense cake.
