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 ↓
Jelly Roll Cake
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.
Prepare the batter
Preheat the oven to 400°F (200°C).
Cream the butter and gradually add the sugar.
Beat in the eggs until well combined.
Sift the flour with the baking powder and add it alternately with the milk to the mixture.
Beat the batter briskly until smooth.
Bake and roll
Spread the batter in thin layers in large shallow tins.
Bake until golden, then spread with currant jelly and roll up.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness as the cake sets.
- Flour
- Forms the main structure of the cake as the batter sets in the oven.
- Butter
- Adds fat for tenderness and flavour in the creamed batter.
- Sugar
- Sweetens the cake and helps tenderise the crumb when creamed with butter.
- Baking powder
- Releases gas in the oven so the thin layers rise and stay light.
- Milk
- Adds moisture and loosens the batter so it spreads thinly.
The step that matters
Spreading the batter in thin layers. Thin layers bake quickly and evenly, so they stay flexible enough to roll without cracking. Thick layers set too firmly and break when rolled around the jelly.
Swap the currant
How well each one fits the dish's main ingredients (sugar, milk, egg, flour, butter):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against sugar, milk, egg, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
