Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
White Sponge 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 six times.
Sprinkle the salt over the egg whites and beat them to stiff peaks.
Gently stir the sugar into the beaten egg whites.
Fold in the flour mixture and then add the flavoring quickly.
Bake and cool
Pour the batter into an ungreased round 3-quart pan with a tube in the center.
Bake for 55 minutes, or until a broom straw inserted comes out clean.
Invert the pan and let it rest on the tube for 1 hour to cool.
Once cool, use a sharp knife to loosen the cake from the pan.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into stiff peaks, they form the airy structure that lifts the cake.
- Flour
- Sifted and folded in, it provides the set structure that holds the foam.
- Sugar
- Stirred into the whites, it sweetens the cake and helps stabilize the foam.
- Cream of tartar
- Sifted into the flour, it acidifies the egg whites so they whip more stably.
The step that matters
Fold in the flour mixture and then add the flavoring quickly. Folding gently keeps the air bubbles in the whipped whites; overmixing deflates the foam and produces a dense, tough cake.
