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 ↓
White Sponge, or Angel Cake
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
Preheat the oven to 350°F (175°C).
Sift the cream of tartar into the flour five or six times and sift the sugar twice.
Add a pinch of salt to the egg whites and whip them until very stiff.
Make the batter
Gradually beat in the sugar, starting from the bottom of the bowl.
Fold in the flour in the same manner, then add the vanilla extract.
Do not stop beating once you start mixing; keep the mixture light.
Pour the batter into an ungreased pan or one lined with paper, preferably one with a tube in the center.
Bake and finish
Bake for 30 to 40 minutes without moving or jarring the pan.
Check for doneness with a broom straw before removing from the oven; do not let it brown too much.
Let the cake stand in the pan for a few minutes, then loosen the sides to let it fall out.
Turn the cake upside down and ice the bottom and sides if desired.

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 provides the cake's light, airy structure.
- All-purpose flour
- Provides the set structure that holds the whipped foam once baked.
- Granulated sugar
- Sweetens the cake and stabilizes the whipped egg white foam.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a stronger, more stable foam.
The step that matters
Folding in the flour. Folding gently keeps the air trapped in the whipped egg whites; stirring or deflating the foam makes the cake dense and flat.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, flour, sugar, cream):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against egg, flour, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
