Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. 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).
Weigh the flour to match the weight of five eggs and sift it to ensure it is dry.
Weigh the sugar to match the weight of eight eggs and pound it until fine.
Separate the egg whites from the yolks.
Make the batter
Beat the yolks with the powdered sugar until well combined.
Whisk the egg whites until stiff peaks form.
Gently fold the egg whites into the yolk mixture until just combined.
Gradually sift in the flour and add your chosen flavoring.
Bake and finish
Butter the cake tins and pour in the batter.
Sift a little sugar over the top of the cakes.
Bake in the preheated oven until pale and set, about 10-15 minutes.
Remove the cakes from the tins while warm and turn them upside down on a wire rack to cool completely.
Store in a closed glass bottle once cooled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lift and structure, while yolks add richness and colour to the sponge.
- All-purpose flour
- Provides the starch that sets during baking to give the sponge its structure.
- Powdered sugar
- Sweetens the batter and helps stabilise the beaten yolks and whites.
The step that matters
Folding the egg whites into the yolk mixture. Folding gently keeps the air beaten into the whites. Stirring vigorously knocks that air out, so the sponge bakes flat and dense instead of light.
