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 Sandwich
Ingredients
Directions
The book says “a hot 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 and sugar together until well combined.
Sift the flour and baking powder together, then gently fold into the egg mixture.
Pour the batter into sandwich tins.
Bake
Bake in the preheated oven until golden and a toothpick comes out clean.

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
- Whisked eggs trap air and provide the main structure that lifts the sponge.
- Sugar
- Sugar sweetens the cake and helps stabilise the whisked eggs as they are beaten.
- Flour
- Flour forms the set crumb structure once the batter is baked.
- Baking powder
- Baking powder releases gas in the oven, helping the sponge rise.
The step that matters
Folding in the flour. Folding gently keeps the air beaten into the eggs. Stirring vigorously knocks out air and gluten develops, which can leave the sponge dense and tough.
