Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. 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 the batter
Preheat the oven to 350°F (175°C).
Beat the egg yolks and sugar together until well combined.
Beat the egg whites until stiff peaks form.
Gently fold the beaten egg whites into the yolk and sugar mixture.
Sprinkle in the flour and baking powder, stirring just enough to combine.
Add your chosen flavoring to taste.
Bake
Spoon the batter into gem pans or small tins.
Bake for about 15-20 minutes or until golden and a toothpick comes out clean.

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 lightness, while yolks add richness and structure.
- Flour
- Provides the structure that holds the airy batter together as it bakes.
- Sugar
- Sweetens the batter and helps stabilise the yolks while they are beaten.
- Baking powder
- Releases gas during baking, helping the cakes rise and become tender.
The step that matters
Folding the egg whites. Folding gently keeps the air beaten into the whites. Stirring or deflating them makes the cakes dense instead of light and springy.
