Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Sponge Cake
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
Sift the flour and cream of tartar together four times.
Beat the egg whites until stiff.
Make the batter
Add the powdered sugar and rose extract to the egg whites.
Gently fold in the sifted flour mixture.
Pour the batter into an ungreased pan.
Bake
Bake at 350°F (175°C) for 40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whites of 11 eggs
- Whipped into a stiff foam that traps air and gives the cake its structure and lift.
- All-purpose flour
- Sets the structure of the cake once heated, giving it body as the foam firms.
- Powdered sugar
- Sweetens the cake and helps stabilize the whipped egg white foam.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a more stable, stiffer foam.
The step that matters
Gently fold in the sifted flour mixture. Folding rather than stirring keeps the air bubbles in the whipped egg whites intact. Overmixing deflates the foam, leaving the cake dense and flat.
