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 ↓
Mixing 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 egg yolks until very light and thick.
Gradually add the sugar while beating continuously, then add the flavoring.
Beat the egg whites until stiff and dry.
Cut and fold part of the egg whites into the yolk and sugar mixture, then fold in part of the flour.
Repeat with the remaining egg whites and flour.
Bake
Bake in an unbuttered pan.

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 trap air that lifts the cake, and the yolks add richness and structure.
- Sugar
- Sweetens the batter and helps the beaten yolks become thick and stable.
- Flour
- Its proteins set with the egg structure, giving the cake its body once baked.
The step that matters
Folding in the egg whites. Stiff whites hold air bubbles that make the sponge rise. Folding gently, in portions, keeps those bubbles intact; vigorous stirring deflates the batter and produces 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.
