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.
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the milk and sifted flour with baking powder, mixing until smooth.
Gently fold in the beaten egg whites.
Bake
Pour the batter into a greased cake pan.
Bake at 350°F (175°C) until a toothpick inserted in the center 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 foam, they trap air and give the cake its light, airy structure.
- Flour
- Its proteins form the gluten network that gives the cake its main structure.
- Baking powder
- Releases gas when heated, helping the batter rise in the oven.
- Butter
- Creamed with sugar, it adds fat that tenderizes the crumb and carries flavor.
- Sugar
- Creamed with butter, it adds sweetness and helps the batter brown lightly.
- Milk
- Adds moisture that hydrates the flour and keeps the crumb soft.
The step that matters
Gently fold in the beaten egg whites.. Whipped whites hold the air that lightens the cake. Stirring hard or folding too roughly knocks that air out, so the cake bakes up dense and flat.
