Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
To Make Small Sponge Cakes
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. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 400°F (200°C).
Sift the flour and pound the sugar until fine.
Make the batter
Beat the egg yolks with the sugar until well combined.
Whisk the egg whites until stiff peaks form.
Gently fold the egg whites into the yolk mixture.
Gradually add the flour and flavoring, mixing just until combined.
Bake and finish
Grease the tins with butter and pour in the batter.
Sprinkle a little sugar over the cakes.
Bake until pale and set, about 10-15 minutes.
Remove from tins while warm and let cool upside down.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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, giving the cakes their light, airy structure as they set.
- All-purpose flour
- Its proteins set on baking, giving the sponge its structure once the batter is cooked.
- Loaf sugar
- Sugar sweetens the cakes and helps the batter stay soft and tender as it bakes.
The step that matters
Folding the egg whites into the yolk mixture. Folding gently keeps the air bubbles in the whipped whites intact. Stirring or deflating them would make the sponge dense instead of light.
