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.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the milk and the yolks of the eggs, mixing well.
Sift together the flour and baking powder, then gradually add to the mixture.
In a separate bowl, beat the egg whites until stiff peaks form.
Fold the beaten egg whites into the batter gently.
Bake and ice
Divide the batter into three or four layers and bake until a toothpick comes out clean.
For the icing, beat the egg whites until stiff, then gradually add the powdered sugar.
Mix in the grated chocolate and vanilla until smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped by beating create air that gives the cake its light, risen structure.
- Butter
- Creamed with sugar, it traps air and adds richness and a tender crumb.
- Flour
- Its proteins set during baking to form the cake's structure.
- Baking powder
- Releases gas when heated, helping the batter rise in the oven.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a light texture.
- Milk
- Adds moisture and helps the batter combine into a smooth mixture.
The step that matters
Folding in the egg whites. Beaten whites hold air that makes the cake rise. Folding gently keeps that air in; stirring hard deflates the batter and yields a dense cake.
