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 ↓
Fruit 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 the batter
Preheat the oven to 350°F (175°C).
Beat the egg yolks, then add sugar, lemon juice, and water.
Mix in the flour combined with baking powder.
Fold in the beaten egg whites gently.
Bake and fill
Pour the batter into shallow pans and bake until golden.
Once cool, split the cake and fill with 1 pint of slightly crushed strawberries.
Finish with meringue
Make a meringue by beating 2 egg whites until stiff, then gradually add 4 tablespoons of powdered sugar.
Spread the meringue on top of the cake and garnish with remaining strawberries.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and color, and help bind the batter.
- Egg whites
- Whipped to foam, they give the sponge its light, airy structure.
- Sugar
- Adds sweetness and helps keep the crumb tender.
- Pastry flour
- Forms the structure that holds the sponge together as it bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Strawberries
- Add fruity flavor and moisture between the cake layers.
The step that matters
Fold in the beaten egg whites gently. The whipped whites trap air that gives the sponge its lift. Stirring hard or vigorously deflates that foam, so the cake bakes up denser and flatter.

Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
