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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Beat the eggs and sugar together for 20 minutes.
Sift the flour 2-3 times, then gradually fold it into the egg and sugar mixture. Flavor as desired.
Bake
Pour the batter into a tube pan and bake for about 40 minutes.

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
- Beaten eggs trap air, forming the foam that lifts and structures the sponge.
- Sugar
- Sweetens the cake and stabilizes the beaten egg foam so it holds its air.
- Flour
- Sets during baking to give the sponge its structure and body.
The step that matters
Fold the flour gently. The flour must be folded in rather than stirred, because vigorous mixing knocks out the air trapped in the beaten eggs. Losing that air leaves the sponge dense instead of light.
