Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Cream Sponge Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the cake
Preheat the oven to 400°F (200°C).
Beat the egg yolks and sugar together until well combined.
Add the egg whites and beat again until fluffy.
Gently fold in the flour until just combined.
Pour the batter into layers and bake in the preheated oven.
Make the cream
For the cream, mix a little milk with the egg white and enough cornstarch to achieve a thick cream consistency.
Sweeten and flavor the cream to your liking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the sponge once the egg foam sets in the oven.
- Eggs
- Whipped foam and yolks give the sponge its lift, airy crumb, and richness.
- Granulated sugar
- Sweetens the batter and helps stabilize the beaten egg foam.
- Cornstarch
- Thickens the milk and egg white mixture into a cream by gelatinizing when heated.
The step that matters
Folding in the flour. Overmixing after the flour goes in develops gluten and deflates the whipped egg foam, making the sponge dense instead of light.
