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 ↓
Delicate 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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and sugar together until light and fluffy.
Gradually add the flour and corn starch, mixing well.
Stir in the milk and baking powder until combined.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
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
- Butter
- Creams with sugar to trap air, giving a tender, fine crumb and rich flavor.
- Egg whites
- Whipped to stiff peaks, they add lift and an airy, light structure to the cake.
- Flour
- Provides the main structure that sets as the cake bakes.
- Corn starch
- Lightens the flour's gluten, producing a softer, more delicate crumb.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
The step that matters
Folding in the egg whites. Whipped egg whites hold the cake's air. Stirring them vigorously deflates the foam, so fold gently with a spatula until just combined to keep the cake light.
