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 together the sugar and butter, then add the egg yolks and mix well.
Stir in the milk.
Sift together the flour and baking powder, then add to the mixture.
In a separate bowl, beat the egg whites until stiff peaks form, then fold into the batter.
Bake and fill
Pour the batter into jelly cake tins and bake until a toothpick comes out clean.
For the filling, beat the egg whites until stiff. Gradually add the sugar, then mix in the chocolate and vanilla.
Spread the filling between the layers and on top of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to add tenderness and richness to the crumb.
- Egg yolks
- Add richness, colour and emulsifying fat to the batter.
- Egg whites
- Whipped to stiff peaks to lighten the batter and give the cake rise.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
The step that matters
Folding the whipped egg whites into the batter. Egg whites hold air only when whipped to stiff peaks. Folding gently keeps that air in the batter, so the cake rises light; stirring vigorously knocks the air out and makes it dense.
