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.
Prepare
Preheat the oven to 350°F (175°C).
Beat the eggs and powdered sugar together lightly.
Stir in the flour until the batter is light and thin enough to spread.
Line a 12 by 18 inch pan with thin brown paper, without greasing it.
Pour the batter into the pan, spreading it thinly, about ½ inch thick.
Bake until done.
Cool and roll
Let cool for a few minutes.
Turn the cake out upside down onto a clean surface while still warm.
Brush the paper with cold water.
Remove the paper carefully.
Spread jelly thinly over the cake.
Roll it up tightly.
Place the outer edge against something to keep it from unrolling until cool.
Finish and serve
Sprinkle with powdered sugar.
Slice.

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
- Whipped with sugar, they trap air and give the thin cake its light structure.
- Flour
- Provides structure so the thin cake holds together when rolled.
- Powdered sugar
- Sweetens the batter and helps give the cake a tender texture.
- Jelly
- Adds sweetness and moisture, and fills the rolled cake.
The step that matters
Rolling the warm cake. The cake must be turned out and rolled while still warm, because warm sponge is flexible and cracks less. Once cool it becomes stiff and tears easily.
“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.
