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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a large bowl, beat the eggs until frothy.
Gradually add the powdered sugar while continuing to beat.
Make the batter
Sift the flour and gently fold it into the egg mixture.
Pour the batter into prepared cake pans.
Bake
Bake for 25-30 minutes or until 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
- Whipped to trap air, giving the cake its light, airy structure.
- Powdered sugar
- Sweetens the cake and helps stabilise the whipped eggs as it is beaten in.
- Flour
- Provides the starch that sets during baking to form the cake's structure.
The step that matters
Folding in the flour. Folding gently keeps the air whipped into the eggs. Vigorous stirring knocks out that air and deflates the batter, leading to a dense, flat 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.
