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 Cake
Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Sift the sugar five times.
Mix and sift the flour, cornstarch, cream of tartar, and salt five times.
Make the batter
Beat the egg whites to a foam, but not too stiff.
Slowly sift in the sugar while beating continuously.
Add the vanilla and fold in the flour mixture gently.
Pour the batter into an unbuttered tube pan.
Bake and cool
Bake in a slow oven at 300°F (150°C) for 1 hour, without opening the oven door for the first 20 minutes.
Remove the cake from the oven and place it upside down on a cake cooler until completely cool.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
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 foam, they trap air that lifts and gives the cake its airy structure.
- Sugar
- Sweetens the cake and, beaten into the whites, helps stabilise the foam.
- Flour
- Provides the starch and protein that set the crumb once the cake bakes.
- Cream of tartar
- Acidifies the egg whites, helping the foam stay stable and hold its volume.
- Cornstarch
- Softens the crumb by diluting the flour's gluten, giving a tender texture.
The step that matters
Folding the flour mixture into the batter. Overmixing knocks air out of the whipped egg whites, so the batter must be folded gently to keep the cake light and high.
