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 ↓

Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Separate the egg whites from the yolks.
Add salt and cream of tartar to the egg whites and beat until very stiff.
Make the batter
Gradually add the sugar and flavorings, beating thoroughly.
Gently fold in the sifted flour.
Bake and cool
Bake in a preheated oven at 350°F (175°C) for 40 to 50 minutes.
Invert the pan to cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a stiff foam that gives the cake its airy, light structure.
- Sugar
- Sweetens the cake and stabilises the whipped egg white foam.
- All-purpose flour
- Provides the gentle starch structure that sets the cake around the air bubbles.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a more stable foam.
The step that matters
Folding in the flour. Over-mixing or stirring vigorously deflates the whipped egg white foam, so the flour must be folded in gently to keep the cake light and tall.
