Why it works: Sugar and flour 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
Preheat the oven to 350°F (175°C).
In a bowl, beat the eggs with the sugar until well combined.
Gradually add one-third of the flour and the baking powder, mixing until smooth.
Spread the batter evenly in a greased baking pan.
Bake and roll
Bake for about 15-20 minutes or until golden.
Remove from the oven, spread jelly quickly over the surface, and roll the cake while it's still hot.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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 structure.
- Sugar
- Sweetens the batter and helps stabilise the whipped eggs.
- Flour
- Forms the cake's structure once it sets in the oven.
- Baking powder
- Releases gas during baking so the sponge rises and stays tender.
The step that matters
Roll the cake while it's still hot. Warm sponge is flexible, so it can be rolled without cracking. Once it cools, it stiffens and tears, so the jelly must be spread quickly after baking.
“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.
