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 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.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the 3 egg yolks and mix well.
Stir in the milk and baking powder.
Gradually add the sifted flour and mix until smooth.
In a separate bowl, beat the 2 egg whites until stiff peaks form.
Fold the beaten egg whites into the batter gently.
Pour the batter into two long cake tins.
Bake and frost
Bake for about 30-35 minutes or until a toothpick comes out clean.
For the frosting, beat the 2 egg whites to stiff peaks.
Gradually add the 1½ cups of sugar and beat until glossy.
Mix in the grated chocolate and vanilla extract.
Spread the frosting on the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness and emulsify the batter; beaten whites add lift and an airy structure.
- Butter
- Fat that tenderises the crumb and carries flavour.
- Sugar
- Sweetens the cake and helps the creamed butter hold air; in the frosting it makes it glossy.
- Flour
- Provides the structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter, making the cake rise.
- Milk
- Adds moisture and hydrates the flour to form the batter.
The step that matters
Fold the beaten egg whites into the batter gently. The whites hold air bubbles that give the cake its lift. Stirring vigorously knocks that air out, leaving a denser, flatter cake.
