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.
Make the batter
Beat the egg yolks until light.
Add the sugar and mix well.
Stir in the water and salt.
Gradually add the flour mixed with baking powder.
Bake and roll
Bake in well-greased long, shallow biscuit tins at 350°F (175°C).
Turn the cake out onto a damp towel on a breadboard.
Spread jelly on top and roll up while warm.
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 eggs trap air, giving the sponge its light, airy structure.
- Sugar
- Sugar sweetens the sponge and helps keep it soft and tender.
- Flour
- Flour sets during baking and gives the sponge its firm structure.
- Baking powder
- Baking powder releases gas in the oven, helping the sponge rise.
The step that matters
Roll up while warm. A freshly baked sponge is flexible when warm. As it cools, the starch sets and the crumb becomes brittle, so it will crack if rolled late.
“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.
