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
Preheat your oven to 400°F (200°C).
Make the batter
In a bowl, stir the sugar into the beaten yolks of the eggs.
Add the sweet cream and flour, along with the baking powder, to make a thin batter.
Beat the egg whites until stiff peaks form, then gently fold them into the batter.
Bake
Pour the batter into hot pans and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness and the whites, beaten to stiff peaks, give the sponge its lift and airy structure.
- White sugar
- Sweetens the batter and helps the yolks hold a smooth, stable texture.
- Sweet cream
- Adds moisture and fat, giving the cake a tender crumb.
- Flour
- Provides the structure that sets the batter as it bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise.
The step that matters
Folding in the egg whites. Whites beaten to stiff peaks trap air that gives the sponge its lift. Stirring them in vigorously knocks that air out, so folding gently keeps the cake light.
