Why it works: Butter and milk 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together in a large bowl.
Add the milk and flour, then mix in the egg whites.
Sift the baking powder into the flour before adding it to the mixture.
Divide the batter into six layers and bake until done.
Make the chocolate layers and filling
For the chocolate layers, add the grated chocolate to the remaining batter and bake in layers.
For the filling, beat the egg whites and sugar to a stiff froth, then fold in the chocolate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness to the crumb as it is creamed with sugar.
- Flour
- Provides the structure that holds the cake together as it sets.
- Egg whites
- Add structure and help bind the batter; whipped whites lighten the filling.
- Baking powder
- Releases gas during baking so the layers rise and become light.
- Grated chocolate
- Adds chocolate flavor and color to the layers and filling.
The step that matters
Beating the egg whites to a stiff froth for the filling. Egg whites must be whipped until stiff so they hold air; under-beaten or greasy whites will not hold their volume, and over-mixing when folding in the chocolate can knock out that air and make the filling dense.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
