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 ↓
Perfection 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.
Prepare
Preheat your oven to 350°F (175°C).
Sift the flour with the baking powder.
Dissolve the corn-starch in the milk.
Make the batter
In a large bowl, beat the butter and sugar together until creamy.
Add the dissolved corn-starch mixture to the butter and sugar, mixing well.
Gradually add the flour and then fold in the beaten egg whites gently.
Avoid beating the mixture in a tin dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped egg whites trap air, giving the cake its light, airy structure.
- Butter
- Creamed with sugar, it traps air and adds richness and tender texture.
- Sugar
- Creams with butter and adds sweetness, helping the cake brown and stay moist.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas during baking, helping the cake rise.
- Corn-starch
- Softens the crumb, giving a finer, more tender texture than flour alone.
The step that matters
Fold in the egg whites gently. Beaten egg whites hold air that gives the cake its lift. Vigorous stirring knocks that air out, leaving a dense, flat cake.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
