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 ↓
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).
Make the batter
In a bowl, beat the sugar and eggs together until very light.
Sift together the flour and baking powder, then add to the egg mixture.
Add flavoring to taste and the boiling water. Beat the mixture thoroughly.
Bake
Pour into a baking pan and bake in the preheated oven.

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
- Beaten with sugar to trap air, giving the cake its light, airy structure.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas during baking, helping the cake rise.
- Fruit sugar
- Adds sweetness and helps the beaten eggs hold a light, airy foam.
- Boiling water
- Adds moisture and helps the batter spread and bake evenly.
The step that matters
Beat the eggs and sugar until very light. Whipping eggs and sugar together traps air bubbles that expand in the oven and give a sponge its light texture. Under-beating leaves a dense cake.
