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 ↓
Never-fail Sponge Cake
Ingredients
Directions
The book says “a moderately hot 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).
Beat the egg whites until stiff peaks form.
Sift the flour four times, adding the baking powder during the last sift.
Make the batter
Add a spoonful of the beaten whites to the yolks and mix well.
Gradually add the sugar, then fold in the remaining beaten whites and flour alternately.
Add the flavoring and boiling water last, mixing well.
Bake
Pour the batter into a prepared pan and bake for 35 minutes.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Eggs
- Whipped whites trap air that lifts the cake, and yolks add richness and structure.
- Sugar
- Sweetens the cake and helps stabilize the whipped egg whites.
- Flour
- Provides the structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
- Boiling water
- Adds moisture and helps create a light, tender crumb.
The step that matters
Folding in the beaten whites. Beaten egg whites hold the air that makes the sponge rise. Stirring them vigorously or letting them deflate loses that air, leaving a dense cake. Fold gently and keep the mixture airy.
