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 ↓
Jelly Roll Cake
Ingredients
Directions
The book says “a medium oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Beat 1 cup of sugar and 3 eggs until stiff.
Gently stir in 1 cup of flour.
Line a baking pan with paper and pour in the batter.
Bake and roll
Bake for 20 to 30 minutes.
Turn the cake out onto a surface dusted with powdered sugar.
Spread jelly over the cake and roll it up.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped to stiff foam, they give the sponge its light, airy structure.
- Sugar
- Sweetens the cake and helps the beaten eggs hold their foam.
- Flour
- Forms the set crumb structure of the sponge once baked.
- Jelly
- Adds sweetness and moisture to the filling inside the rolled cake.
The step that matters
Gently stir in the flour. Overmixing once flour is added develops gluten and deflates the whipped egg foam, making the cake dense and prone to cracking when rolled.
