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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Weigh the eggs and use their weight in sugar.
Use 6 ounces of flour.
Make the batter
Beat the yolks with the flour.
In a separate bowl, beat the egg whites until very stiff.
Gradually mix the beaten egg whites with the yolk and flour mixture.
Beat the combined mixture well for 30 minutes.
Pour the batter into a baking pan.
Bake
Bake in a preheated oven at 400°F (200°C) for 1 hour.

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, while yolks add richness and structure.
- Sugar
- Sweetens the cake and helps stabilize the beaten egg whites.
- All-purpose flour
- Provides the protein and starch that set the cake's structure as it bakes.
The step that matters
Gradually mixing the whites into the yolk mixture. Beaten egg whites hold air that makes the sponge rise. Mixing gently and gradually keeps that air from being knocked out, so the cake stays light.
