Why it works: Flour and sugar 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 ↓

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).
Separate the egg whites and yolks.
Beat the egg whites until stiff peaks form.
Make the batter
In another bowl, beat the egg yolks with sugar until light and fluffy.
Gently fold the flour into the yolk mixture.
Carefully fold in the beaten egg whites until just combined.
Pour the batter into a greased cake pan.
Bake
Bake for 25-30 minutes or until a toothpick comes out clean.

Flour and egg 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 for lift, and yolks add richness and structure as the cake sets.
- Flour
- Provides the starch and gluten network that sets the cake's structure as it bakes.
- Sugar
- Beaten with the yolks to add sweetness and help create a light, fluffy texture.
The step that matters
Carefully fold in the beaten egg whites. Folding gently keeps the air bubbles in the whipped whites intact. Those bubbles provide the rise, so overmixing or deflating the batter leads to 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.
