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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Beat the egg whites to a stiff froth.
In a separate bowl, combine sugar and sifted flour with baking powder.
Make and bake
Gently fold the flour mixture into the egg whites.
Add vanilla for flavor.
Pour the batter into a new tin and bake for 40 minutes at 350°F (175°C).

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 traps air and gives the cake its light, airy structure.
- Flour
- Forms the cake's framework once set, giving it body to hold the airy foam.
- Sugar
- Sweetens the cake and helps stabilize the whipped egg white foam.
- Baking powder
- Releases gas in the batter to help the cake rise in the oven.
The step that matters
Gently fold the flour mixture into the egg whites. Stirring vigorously or overmixing deflates the whipped foam, removing the trapped air that makes the cake rise and stay light.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, sugar, flour):
- Raisinfits better
- Vanillathe original
- Lemonfits less well
- Figfits less well
Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
