Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Sponge Cakes, Small
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Ensure the flour is perfectly dry and sift the sugar.
Combine the eggs and sugar in a basin over a saucepan of hot water.
Whisk the mixture until it is white and creamy, about 15 to 20 minutes.
Make and bake the cakes
Quickly add the flour and flavoring, mixing lightly with a spoon.
Butter the tins well, pour in the batter, and sift a little sugar over the cakes.
Bake in a quick oven at 400°F (200°C) until pale and not too colored.
Finish and store
Remove the cakes from the tins before they cool and turn them onto a wire rack until completely cool.
Store in a closed tin canister or wide-mouthed glass bottle.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked with sugar to trap air, giving the sponge its light, airy structure.
- Flour
- Provides the structure that sets the sponge once baked.
- Castor sugar
- Sweetens the cake and helps stabilize the whisked egg foam.
The step that matters
Quickly add the flour and flavoring. Once the eggs are whisked, air bubbles are easily knocked out. Folding the flour in gently and quickly keeps the batter light, so the cakes rise well rather than turning dense.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, flour, egg):

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