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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the cake batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add a little flour to bind the mixture.
Alternately add the milk and remaining flour, mixing well.
Gently fold in the beaten egg whites.
Finally, add the baking powder and mix until just combined.
Pour the batter into three greased cake pans.
Bake and make the filling
Bake for 25-30 minutes or until a toothpick comes out clean.
For the filling, combine the egg yolks, sugar, milk, and chocolate in a double boiler.
Simmer until smooth, stirring constantly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten and folded in to give the cake lift and an airy structure.
- Butter
- Creamed with sugar to trap air and give a tender, rich crumb.
- Sugar
- Sweetens the cake and helps tenderise it when creamed with butter.
- Flour
- Provides the structure that sets the cake as it bakes.
- Baking powder
- Releases gas during baking so the cake rises.
- Egg yolks
- Add richness and help thicken the chocolate filling as it cooks.
The step that matters
Simmering the chocolate filling. Stirring constantly over gentle heat in a double boiler keeps the egg yolks from scrambling and gives a smooth, thickened filling.
