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 ↓

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.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the egg yolks and mix well.
In a separate bowl, combine the flour and baking powder.
Gradually add the flour mixture to the creamed mixture, alternating with the sweet milk.
In another bowl, beat the egg whites until stiff peaks form, then fold them into the batter.
Stir in the dissolved chocolate once it has cooled.
Bake
Pour the batter into a greased cake pan and bake for 30-35 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and add richness and tenderness to the crumb.
- Egg whites
- Whipped to stiff peaks, they add lift and an airy, light structure to the batter.
- Egg yolks
- Add richness, moisture and emulsifying fat that help bind the batter.
- All-purpose flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter, helping the cake rise and become light.
- Chocolate
- Adds cocoa flavour, colour and some moisture to the cake.
The step that matters
Folding in the egg whites. Whipped whites hold air that gives the cake its lift. Stirring them in vigorously deflates the foam, so the cake bakes up dense instead of light.
