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 30-35 minutes or until a toothpick comes out clean.
For the frosting, beat the 2 egg whites to stiff peaks.
Gradually add 1½ cups sugar and mix until glossy.
Fold 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 whites, whipped to stiff peaks, lighten the batter for a tender crumb.
- Butter
- Creamed with sugar, it traps air and adds fat for a tender, moist texture.
- Sugar
- Sweetens the cake and, when beaten with egg whites, helps the frosting become glossy and stable.
- Flour
- Provides the structure that sets the cake as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Grated chocolate
- Adds chocolate flavour and richness to the frosting.
The step that matters
Folding in the beaten egg whites. Folding gently keeps the air whipped into the whites. Stirring or overmixing deflates the batter, leading to a denser cake that rises less.
