Why it works: Flour and sugar 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 ↓
Rolled Jelly 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat your oven to 350°F (175°C).
In a bowl, beat the eggs until fluffy.
Gradually add the sugar and continue to beat until well combined.
Sift the flour and baking powder together, then fold into the egg mixture.
Pour the batter into a greased baking pan and spread evenly.
Bake and roll
Bake for about 15-20 minutes or until golden brown.
Once baked, spread jelly over the cake while it is still hot.
Roll the cake up carefully and let it cool before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten until fluffy, they trap air that gives the sponge its light structure.
- Flour
- Provides the structure that holds the sponge together so it can be rolled.
- Sugar
- Sweetens the cake and, beaten with the eggs, helps stabilize the foam.
- Baking powder
- Releases gas during baking so the cake rises and stays tender.
- Jelly
- Adds sweetness and moisture to the filling inside the rolled cake.
The step that matters
Rolling the cake while it is still hot. Warm sponge is flexible and less likely to crack. If it cools fully before rolling, it becomes brittle and can split, so roll it promptly after spreading the jelly.
