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 ↓
Roll Jelly 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.
Make the batter
Beat the egg yolks and mix with sugar.
Stir in the flour until combined.
In a separate bowl, beat the egg whites until stiff peaks form, then gently fold into the batter.
Spread the batter onto two large baking sheets.
Bake and roll
Bake at 400°F (200°C) until lightly golden.
While hot, spread jelly over the cake and roll it tightly.
Wrap in a towel until ready to cut.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites whipped to stiff peaks trap air, giving the cake its light, airy structure.
- Flour
- Provides the starch and protein that set during baking to form the cake's body.
- Sugar
- Sweetens the cake and helps the yolks whip to a smooth, stable batter.
- Jelly
- Adds sweetness and moisture to the filling inside the rolled cake.
The step that matters
Roll the cake while hot. Warm sponge is flexible, so it rolls without cracking. Once it cools, the cake stiffens and tears, so the jelly spreading and rolling should happen promptly 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.
