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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, mix the corn-starch, flour, and baking powder together.
In another bowl, cream the butter and sugar together.
Add the flour mixture to the butter and sugar alternately with the milk.
Fold in the beaten egg whites and season with lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten whites trap air, giving the sponge its light, airy structure.
- Butter
- Creamed with sugar, it adds richness and tenderness to the crumb.
- Sugar
- Creamed with butter, it adds sweetness and helps give the cake its texture.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Corn-starch
- Softens the flour's gluten, producing a more tender, delicate crumb.
- Baking powder
- Releases gas during baking so the cake rises.
The step that matters
Fold in the beaten egg whites. Folding gently keeps the air trapped in the whites; stirring vigorously deflates the batter and produces a dense, flat cake.
