Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Cream Sponge
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 sponge
Preheat the oven to 400°F (200°C).
Beat the egg yolks with the sugar and lemon juice until well combined.
Whip the egg whites until stiff peaks form.
Gently fold the whipped egg whites into the yolk mixture.
Sift the flour and gently stir it into the batter.
Pour the batter into jelly tins and bake until golden.
Make the cream and icing
For the cream, mix the yolks of 2 eggs with the milk, sweetening to taste, and add a pinch of salt and vanilla.
For the icing, beat the 2 egg whites until stiff, then gradually add the powdered sugar and lemon juice to taste.

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 and set the sponge, giving it its light structure.
- Flour
- Provides the starch and gluten that set the cake's structure as it bakes.
- Sugar
- Sweetens the batter and helps the yolks whip to a stable, smooth mixture.
- Milk
- Adds moisture and richness to the cream filling.
The step that matters
Folding the whipped egg whites into the yolk mixture. Folding gently keeps the air in the whites. Stirring or beating hard deflates the foam, and the sponge then bakes flat and dense.
