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.
Prepare
Weigh the flour to match the weight of the eggs and the sugar to match the weight of eight eggs.
Ensure the flour is dry and the sugar is well pounded and sifted.
Separate the egg whites from the yolks.
Make the batter
Beat the yolks with the sugar until combined.
Whisk the egg whites until stiff peaks form, then gently fold them into the yolk mixture.
Gradually sift in the flour and add the flavoring, mixing just until combined.
Bake and store
Butter the cake tins well and pour in the batter.
Sift a little sugar over the top.
Bake in a preheated oven at 400°F (200°C) until pale and set, avoiding browning.
Remove the cakes from the tins while warm and turn them upside down to cool completely.
Store in a closed tin canister or wide-mouthed glass bottle.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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 give the sponge its light, airy structure, while yolks add richness.
- All-purpose flour
- Provides the starch and gluten that set the crumb once the cake is baked.
- Powdered sugar
- Sweetens the cake and helps create a fine, tender crumb.
The step that matters
Folding the whites into the yolk mixture. Whisked egg whites trap air that makes the sponge rise. Folding gently preserves that air; stirring or deflating the whites produces a dense, flat cake.

Fit is the average pairing score against egg, flour, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
