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 ↓
Easy Sponge Cake
Ingredients
Directions
The book says “a very 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).
Line a large, well-greased cake tin with buttered paper.
Grease a large mold with clarified butter and dust it with a mixture of equal parts sugar and flour.
Make the batter
Whisk the eggs together until well combined.
Add the sugar and whisk for about 12 minutes.
Gently fold in the flour with a metal spoon.
Bake
Pour the batter into the prepared tin and bake for about 45 minutes.
Do not open the oven door for the first 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked to trap air, giving the cake its light, airy structure.
- Sugar
- Whisked with the eggs to add sweetness and help hold the foam together.
- Flour
- Folded in gently to form the cake's structure as the batter sets in the oven.
The step that matters
Folding in the flour. Flour must be folded in gently with a metal spoon so the air whisked into the eggs is not knocked out. Overmixing deflates the foam and produces a dense, flat sponge.
