Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Cream 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.
Make the batter
Preheat the oven to 350°F (175°C).
In a large bowl, beat the eggs and sugar thoroughly.
Add the flour, baking powder, boiling water, and salt; mix well.
Flavor the batter with Royce's lemon extract.
Pour the batter into thick layers in prepared cake pans.
Bake and assemble
Bake until golden and a toothpick comes out clean.
Once cooled, layer the cakes with whipped cream.
Make the frosting
For the frosting, beat the egg white and gradually add confectioners' sugar until smooth.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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 sponge its light, airy structure.
- Sugar
- Sweetens the cake and helps stabilise the beaten eggs.
- Flour
- Forms the cake's main structure once the batter is baked.
- Baking powder
- Releases gas during baking, helping the cake rise.
- Whipped cream
- Adds moisture and richness between the cake layers.
The step that matters
Beating the eggs and sugar thoroughly. Air beaten into the eggs and sugar is what lifts a sponge. If the mixture is under-beaten, the batter stays dense and the cake rises poorly.
