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 ↓
Marble and Feather Cake
Ingredients
Directions
The book says “a medium oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream butter and sugar together.
Add egg yolks one at a time, beating until creamy.
Mix in 1 cup of flour sifted with ½ teaspoon baking powder.
Add milk and beat until creamy.
Sift in another cup of flour with 1½ teaspoons baking powder.
Stir in egg whites and flavor with lemon extract.
Layer and bake
Pour one-third of the batter into a greased and floured cake tin.
Add red food coloring and 1 teaspoon vanilla extract to the remaining batter and mix well.
Drop half of the pink batter in spoonfuls over the white batter in the tin.
Stir 1 tablespoon of grated chocolate or cocoa into the remaining batter and pour it over the first two layers.
Bake in a moderate oven at 350°F (175°C) for about 50 minutes to 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a tender crumb by coating flour particles and carrying flavour.
- Sugar
- Adds sweetness and helps the creamed mixture trap air for a lighter texture.
- Egg yolks
- Add richness and emulsify the batter, helping it hold together smoothly.
- Flour
- Provides the structure that sets the cake as the proteins firm up in the oven.
- Baking powder
- Releases gas during baking, causing the batter to rise and become light.
- Milk
- Adds moisture and loosens the batter so it spreads evenly in the tin.
The step that matters
Dropping the pink batter over the white. Spoon the batter onto the white layer gently and avoid stirring it in. Overmixing blends the colours into an even batter, so the marbled streaks disappear and the cake bakes with a uniform look.
