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 ↓
Golden 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).
Beat the egg whites until very stiff.
Beat the yolks until the bubbles look fine.
Add the sugar to the yolks and beat until dissolved.
Gently fold in the beaten egg whites.
Gradually add the flour and mix until combined.
Pour the batter into greased brick‑shaped tins.
Bake and serve
Bake for nearly an hour until golden.
For a moister cake, line the tins with a paste made of flour and water before pouring in the batter.

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 whites give the cake its light, airy structure, and the yolks add richness.
- Sugar
- Sweetens the batter and helps the yolks become smooth and fine-textured when beaten.
- Flour
- Provides the set structure that holds the cake's airy foam once baked.
The step that matters
Folding in the beaten egg whites. Whites are a foam that holds air, which is what makes the cake rise. Stirring them in roughly or overmixing knocks out that air, leaving a dense cake.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
