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 oven to 350°F (175°C).
Sift cream of tartar into flour five or six times and sift sugar twice.
Make the batter
Add a pinch of salt to egg whites and whip until very stiff.
Gradually add sugar to whipped egg whites, beating it in from below.
Fold in flour in the same manner, then add vanilla extract.
Do not stop beating after mixing begins; keep mixture light.
Bake and finish
Pour batter into a perfectly bright ungreased pan or one lined with paper, preferably one with a tube in the center.
Bake for 30 to 40 minutes without moving or jarring the pan.
Check for doneness with a broom straw before removing from oven; do not let it brown too much.
Let cake stand in pan for a few minutes, then loosen it around sides to let it fall out.
Turn cake upside down and ice 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 gives the cake its light, airy structure.
- Sugar
- Sweetens the cake and helps stabilize the whipped egg white foam.
- All-purpose flour
- Provides the structure that holds the cake together once baked.
- Cream of tartar
- Acidifies the egg whites, helping the foam hold its volume and stay stable.
- Vanilla extract
- Adds aroma and flavor to the finished cake.
The step that matters
Folding in the flour and keeping the batter light. The whipped egg white foam is the only leavening in an angel cake. Overmixing or deflating it with heavy stirring knocks out air, producing a dense, squat cake instead of a light, tall one.
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.
