Why it works: Flour and corn are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,165 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
White Sponge Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Sift together the flour, corn starch, and baking powder.
Add the sugar and rose extract, then fold in the whipped egg whites.
Mix thoroughly and pour into a well-buttered cake tin.
Bake
Bake in a preheated oven at 400 °F (200 °C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to foam, they trap air and give the sponge its light, airy structure.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Corn starch
- Softens the crumb and makes it more tender than flour alone.
- Sugar
- Sweetens the cake and helps keep the crumb moist and fine.
- Baking powder
- Releases gas in the oven, helping the cake rise.
The step that matters
Folding in the egg whites. Whipped egg whites hold the air that lifts the sponge. Stirring them in vigorously knocks out that air, leaving a dense cake. Fold gently so the batter stays light.
