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).
Grease a cake tin and dust it with a mixture of 1 teaspoon caster sugar and 1 teaspoon rice flour.
Make the batter
Beat the eggs and caster sugar over hot water until creamy.
Quickly mix in the flour.
Half fill the prepared tin with the batter.
Bake
Bake the cake for about one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped with sugar to trap air, giving the sponge its light, risen structure.
- Castor sugar
- Sweetens the cake and helps the beaten eggs hold a stable, creamy foam.
- Flour
- Sets during baking to give the sponge its body once the air bubbles are in place.
The step that matters
Quickly mix in the flour. Once the flour is added, further stirring develops gluten and knocks out the air beaten into the eggs. Folding in the flour quickly and gently keeps the batter light so the sponge rises well.
