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 the batter
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the milk and mix well.
In a separate bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture, mixing until smooth.
Fold and bake
In another bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
Pour the batter into prepared cake pans and bake for 25-30 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
- Creamed with sugar to trap air and give the cake a tender, rich texture.
- Sugar
- Creamed with butter to aid aeration and add sweetness and browning.
- Flour
- Forms the structure that holds the cake's crumb once baked.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
- Egg whites
- Beaten to stiff peaks and folded in to lighten the batter and add rise.
- Egg yolks
- Add richness, fat and emulsifying power that help set the crumb.
The step that matters
Gently fold the egg whites into the batter. Beaten whites hold air that gives the cake its rise. Vigorous stirring deflates them, leading to a dense, flat layer.
