Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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 chocolate mixture
Combine 2 squares of Baker's chocolate, 1 egg yolk, ½ cup sugar, and ½ cup milk in a saucepan; boil together, then let cool.
Make the batter
Beat 2 eggs with 1 cup sugar until well combined.
Add ½ cup butter and ½ cup milk to the egg mixture.
Sift in 2 teaspoons baking powder and mix until smooth.
Stir the cooled chocolate mixture into the cake batter.
Bake and assemble
Pour the batter into a greased cake pan and bake at 350°F (175°C) until a toothpick comes out clean.
Layer white icing between the cake layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps it brown and keep moisture.
- Baker's chocolate
- Provides the chocolate flavor and color of the cake.
