Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the sugar, butter, and eggs together.
Add the milk and mix well.
Sift the baking powder and flour together, then mix into the batter.
Pour the batter into a long pan, spreading it evenly.
Bake and roll
Bake until golden and set.
Turn the cake out onto a clean cloth.
Spread with jelly or jam, then roll it up in the cloth.
Let it cool before slicing across the end.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the sponge together when it is rolled.
- Eggs
- Add structure and lift, helping the sponge set and stay flexible.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps it brown while creaming adds air to the batter.
- Baking powder
- Releases gas in the oven so the cake rises and stays light.
- Milk
- Adds moisture so the batter spreads and bakes evenly.
The step that matters
Turn the cake out and roll it while warm. Rolling the cake in the cloth while it is still warm keeps it flexible, so it can curl without cracking. Once it cools fully, the sponge becomes stiff and is more likely to split.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
