Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Velvet Sponge Cake
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Beat the yolks of the eggs lightly, then add the sugar and beat for 15 minutes.
Add the beaten egg whites and the boiling water just before incorporating the flour.
Mix in the baking powder and lemon flavoring.
Pour the batter into three cake pans.
Bake
Bake at 400°F (200°C) until a toothpick inserted in the center comes out clean.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness, and beaten whites trap air that lifts the cake's structure.
- Flour
- Provides the structure that holds the risen cake together as it sets.
- Sugar
- Sweetens the cake and helps keep the crumb tender.
- Baking powder
- Releases gas in the batter, making the cake rise.
- Boiling water
- Adds moisture to the batter.
The step that matters
Add the whites and boiling water just before the flour. Egg whites trap air that makes the cake rise. Adding them just before the flour and mixing only until combined keeps that air from collapsing, so the cake stays light.

Fit is the average pairing score against sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
