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 ↓
Velvet 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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Beat the egg whites until stiff, adding the cream of tartar.
Sift together the flour and sugar, then beat them with the egg whites.
In a separate bowl, beat the egg yolks until creamy, then add to the mixture.
Gently fold in the sifted flour and almond extract.
Bake
Pour the batter into angel food pans and bake for 45 minutes.

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 that traps air, giving the cake its light structure.
- Egg yolks
- Add richness and fat, tenderizing the crumb and adding moisture.
- Flour
- Provides the starch and protein that set the cake's structure as it bakes.
- Sugar
- Sweetens the cake and softens the crumb while helping stabilize the whipped whites.
The step that matters
Gently fold in the sifted flour and almond extract. Folding rather than stirring keeps the air bubbles in the beaten egg whites intact. Those bubbles make the cake rise and stay light, so deflating them leaves a dense result.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
