Why it works: Sugar and egg are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Roll Jelly Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Sift together sugar, baking powder, and salt in a mixing bowl.
Beat the eggs until foamy.
Stir the eggs into the sifted mixture and beat well.
Bake
Prepare two medium-sized buttered shallow tins.
Pour the batter into the tins.
Spread the batter very thin.
Bake immediately in a 400°F (200°C) oven.
Roll and finish
Once done, turn the cake out onto a cloth.
Spread the beaten jelly over the hot cake.
Roll the cake quickly.
Cover the rolled cake with a cloth.

What each ingredient does
- Eggs
- Beaten eggs trap air and give the thin sponge its light, flexible structure.
- Sugar
- Sweetens the cake and helps give it a tender crumb.
- Baking powder
- Releases gas in the batter so the thin cake rises and stays light.
- Jelly
- Adds sweetness and moisture, and its filling keeps the rolled cake moist.
The step that matters
Roll the cake quickly. Once baked, the sponge is hot and pliable, but it stiffens as it cools and can crack when rolled. Rolling while still hot, after spreading the jelly, keeps it flexible and prevents cracking.
