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 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a mixing bowl, beat the eggs well.
Add the sugar to the eggs and mix until combined.
Sift in the flour and baking powder, then mix until smooth.
Pour the batter into a shallow square pan and bake until golden.
Fill and roll
Once baked, remove from the oven, spread jelly over the top, and roll the cake while it's still warm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs trap air and give the cake its light, sponge-like structure.
- Sugar
- Sweetens the cake and helps keep it tender and moist.
- All-purpose flour
- Provides the starch and gluten that set the cake's structure as it bakes.
- Baking powder
- Releases gas during baking, helping the cake rise.
- Jelly
- Adds sweetness and fruity flavor to the filling inside the rolled cake.
The step that matters
Roll the cake while it's still warm. A warm sponge is flexible, so it can be rolled without cracking. Once it cools, it becomes stiff and is more likely to crack along the roll.
