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 Cake
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
Preheat the oven to 400°F (200°C).
Make the batter
Beat the eggs until the yolks and whites are well mixed.
Add the powdered sugar and beat for 15 to 20 minutes until thick and light.
Stir the baking powder into the flour.
Gradually add the flour and cold water, stirring lightly.
Bake
Pour the batter into sponge tins or a shallow pan and bake until golden.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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 to trap air, giving the sponge its light, airy structure.
- Powdered sugar
- Beaten with the eggs to build volume and add sweetness and tenderness.
- All-purpose flour
- Provides the structure that sets the cake as it bakes.
- Baking powder
- Releases gas in the batter to help the cake rise.
- Cold water
- Adds moisture so the batter loosens and stays tender.
The step that matters
Folding in the flour and water. Stirring too vigorously knocks out the air whipped into the eggs and sugar, so the sponge rises less and turns dense. Stir lightly and only until combined.
