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 ↓
Small Sponge Cakes
Ingredients
Directions
The book says “a moderately hot 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).
Grease small sponge cake tins with clarified butter.
Dust the tins with a mixture of equal parts sugar and flour.
Make the batter
Whisk the eggs thoroughly.
Add the sugar to the eggs.
Whisk again until light and frothy, about 12 minutes.
Sift the flour.
Gently fold the sifted flour into the egg mixture with a metal spoon.
Fill the tins three-quarters full.
Bake
Bake for 12 to 15 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 sponge its light, airy structure.
- Flour
- Folded in gently to give the sponge its set structure once baked.
- Castor sugar
- Whisked with the eggs to help stabilise the foam and add sweetness.
The step that matters
Whisking the eggs and sugar until light and frothy. The foam made by whisking holds the air that makes the sponge rise. If it is under-whisked, the cake comes out dense; if flour is folded in too roughly, the air is knocked out.
“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.
