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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the cake
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together.
Add the eggs, beating the yolks and whites separately.
Mix in the milk.
Sift the flour with the baking powder and add it to the mixture along with the vanilla.
Pour the batter into a flat pan and bake for about 30-35 minutes.
Frost and finish
For the frosting, beat the egg whites to a froth.
Gradually add the powdered sugar and chocolate to the egg whites.
Once the cake has cooled for 30 minutes, spread the frosting on top.
Return the cake to the oven with the door open for 10-15 minutes to harden the frosting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake up as it bakes.
- Butter
- Adds richness and tenderness through fat that coats the flour.
- Eggs
- Give structure and lift when whites are beaten separately, and add richness from the yolks.
- Baking powder
- Releases gas during baking, so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps it brown and stay tender.
- Egg whites
- Whipped to a froth, they form the airy base of the frosting.
The step that matters
Returning the cake to the oven to harden the frosting. Heating the frosting briefly with the door open dries and sets its surface. Too long or too hot can overbake the cake or scorch the frosting, so watch it closely.
