Why it works: Milk and butter 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 ↓
A Wholesome Sponge-cake
Ingredients
Directions
The book says “a moderately quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Sift the flour and powdered sugar together.
Whisk the egg whites until stiff.
Make the batter
In a large bowl, beat the egg yolks until light.
Gradually stir in the powdered sugar and milk.
Gently fold in the egg whites.
Stir in the flour and baking powder until well combined.
Bake
Pour the batter into a well-buttered mold.
Bake at 350°F (175°C) for one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air for lift, while the yolks add richness and structure.
- All-purpose flour
- Its proteins set into the cake's structure as it bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Powdered sugar
- Adds sweetness and a fine, tender crumb to the batter.
- Milk
- Adds moisture and loosens the batter.
The step that matters
Folding in the egg whites. The air bubbles in the whipped whites give this cake its lift. Stirring hard or folding roughly deflates them, leaving a dense cake, so fold gently until just combined.
“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.
