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 ↓
Cornstarch Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Cream together the butter and sugar.
Make the batter
Dissolve the cornstarch in the milk and add it to the butter and sugar mixture.
Sift the baking powder into the flour and stir it into the mixture.
Fold in the beaten egg whites.
Bake
Pour the batter into a baking pan and bake immediately.

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 cake lightness and structure as they set.
- Cornstarch
- Tenderizes the crumb, producing a finer, softer texture than flour alone.
- Butter
- Adds fat for richness, tenderness, and flavour.
- Sugar
- Sweetens the cake and helps create a tender crumb and light browning.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Baking powder
- Releases gas when moistened and heated, causing the batter to rise.
The step that matters
Bake immediately after mixing. Baking powder starts releasing gas as soon as it gets wet. If the batter waits before going into the oven, some of that lift is lost and the cake may be denser.
