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.
Make the cake
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the milk and mix well.
Stir in the flour and baking powder.
Fold in the whites of 4 eggs.
Pour the batter into a greased cake pan and bake until done, like a jelly cake.
Make the filling
For the filling, beat the whites of 3 eggs to stiff peaks with 2 tablespoons of sugar.
Mix in the grated chocolate and 2 tablespoons of powdered sugar.
Assemble
Spread the filling between the warm cake layers and on top and sides, allowing it to dry on the stove.

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's crumb together as it bakes.
- Eggs
- Whites are whipped and folded in to lighten the batter and add structure.
- Baking powder
- Releases gas as it heats, making the cake rise and become light.
- Butter
- Creamed with sugar to add fat, tenderness and richness to the crumb.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Grated chocolate
- Adds chocolate flavour and richness to the filling.
The step that matters
Beating the egg whites to stiff peaks for the filling. Egg whites only hold air when fully whipped and free of fat or yolk. Under-beaten or greasy whites will not stand up, so the filling will be runny and will not set properly when the chocolate is folded in.
“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.
