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 your oven to 350°F (175°C).
In a large bowl, beat the egg whites until stiff peaks form.
In another bowl, cream the butter and powdered sugar together until light and fluffy.
Gradually add the flour to the butter mixture, mixing well.
In a small bowl, combine the cream of tartar and baking soda with the sweet milk, then add to the mixture.
Fold the egg whites into the batter gently.
Add flavoring and a pinch of salt, mixing until just combined.
Bake
Pour the batter into a greased cake pan 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
- Egg whites
- Whipped to stiff peaks, they lighten the batter and give the cake an airy crumb.
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Creamed with sugar to trap air and add richness and tender texture.
- Powdered sugar
- Sweetens the cake and helps create a fine, light texture when creamed with butter.
- Cream of tartar
- Acidifies the batter and stabilizes the whipped egg whites.
- Baking soda
- Reacts with the acid in the batter to produce gas that makes the cake rise.
The step that matters
Folding in the egg whites. Stirring vigorously deflates the whipped egg whites, which are the main source of lift. Folding gently keeps the air bubbles intact so the cake stays light and rises well.
